FuzzFace2 Posted February 10, 2020 Share Posted February 10, 2020 Ok a buddy has 2 lets call them 80 to 86 short bed trucks. Both are 2 wheel trucks. We cant see the VIN on the dash on either truck. 1 has the newer glass and it covers the VIN, the other has dirt over it and cant get down there to clean it. I have asked him to give me the VIN numbers off the titles so I know what year the 2 trucks are, what motor, transmissions, rear axle & ratios they started life with. The parts truck has the newer "F100" badges on the fenders. Cant read the cert sticker in the door jamb and dirty VIN on dash. The under hood sticker has 3.8 information? Looks like the radiator support & 1 fender was replaced. Looks to be a factory 300/auto. not a feed back system as I don't see the hole in the firewall for the wires. Now what is close to that area is where the speed control wires & vacuum hose comes out. The speed control box looks to be bolted to the lower part of the dash where the feed back box would be. Truck has a 9" rear axle. The project truck has no cert sticker in door jamb, glass blocks VIN on dash. No fender badges Radiator sticker also has 3.8/auto but think the support has been replaced also. The truck has a 302/auto that I sure was dropped in it as the oil pan (front sump) is sitting on the cross member. This truck did have a feed back system as the hole in firewall is there with cut wires seen and the box bolted to the lower part of the dash inside. This truck is blue metal flake but has a red interior? Dome light has map lights in it, holding up what is left of the head liner. Truck has a 8.8 rear axle. So the school part: Any way to tell years with out a VIN? The HVAC control, both have AC, is different between them. On a 302 motored truck is the oil pan a front or rear sump? What frame mounts did the 302 trucks use and are they the same as other size motors used in our trucks? How many different blue metal flake colors were use in our trucks. It looks to be the same blue as the 2 or 3 of our members trucks. If the truck has electric locks did it also have the pin type rod sticking out the top of the door panel too? That is all I can think of at this time. As always thanks for any information you can give. Dave ---- Link to comment Share on other sites More sharing options...
Rembrant Posted February 10, 2020 Share Posted February 10, 2020 The parts truck has the newer "F100" badges on the fenders. Well, that narrows that particular truck down to being a 1982-1983 only, assuming the emblems are original/correct. Assume it does not have the so-called Swiss Cheese frame? So the school part: Any way to tell years with out a VIN? The HVAC control, both have AC, is different between them. On a 302 motored truck is the oil pan a front or rear sump? What frame mounts did the 302 trucks use and are they the same as other size motors used in our trucks? I think the SBF engine mounts would be used only with the 302 and 351, but they should be the same for all years of the Bullnose (and after) as far as I know. I didn't think they were used with any other engines, but somebody on here may correct me on that. The 302 oil pan (1980+) was considered a rear sump pan, but as Bill (I think) mentioned earlier, it was more of a middle sump pan. A front sump pan would indicate a pre-1980 pickup or a car model...

Rembrant Posted February 10, 2020 Share Posted February 10, 2020 Truck has a 8.8 rear axle. The 8.8 rearend showed up in 1983. I'm not sure if it was in ALL 1983 models, but I know that is when they were introduced to replace the 9" rearend as the standard. Link to comment Share on other sites More sharing options...
Rembrant Posted February 10, 2020 Share Posted February 10, 2020 302 and 351w engine mounts were the same from 1980-1996 according to LMC. That's all I've got Dave! Link to comment Share on other sites More sharing options...
Gary Lewis Posted February 10, 2020 Share Posted February 10, 2020 Truck has a 8.8 rear axle. The 8.8 rearend showed up in 1983. I'm not sure if it was in ALL 1983 models, but I know that is when they were introduced to replace the 9" rearend as the standard. The 9" was used through '86, as shown here, but the 8.8 was more common as of 1983: A partial VIN is stamped on the top of the frame roughly above the passenger's feet. But I documented that in the Dad's truck build if you want to get an exact location. And you can probably read the VIN tag by removing the dash pad and using a light and a mirror. My brother was able to do that when I sold a truck with the wrong windshield. The Windsor perches were used for 255, 302, and 351W for all years. The A/C controls were 1980 - 82 and 83 - 86, as shown on the Swapping Controls tab here: http://www.garysgaragemahal.com/hvac-systems.html Link to comment Share on other sites More sharing options...

I did see somebody mention on FB one day that there was a determining factor. Something like all 2wd F150's with 351w engines still got the 9" rear diff until 1986, as did all of the F150 4x4 trucks with the Non-OD 4spds? And all other F100/F150's 1983 and later got the 8.8?

Cory - I suspect whatever someone has said about which trucks got what was a very generic answer. I say that because it was anything but simple. The pages below is from Ford's 1986 Light Truck Book. And you can tell 8.8's from 9" axles because the 8.8's have a 3.55 ratio and the 9's have a 3.50 ratio. But as no one will every find these pages via a Google search, I'm going to attempt to translate them into words. But, if I messed something up PLEASE correct me! And, by the way, I have pages from the previous years that provide the same info. But, as you can see, this is complex and I don't want to spend the time to figure out if there were differences between the years. From what I see, all F150's got the 8.8" except these trucks which got 9" axles: 4x2: 49 States 5.0L (302) EFI V-8 - 4 SPD MAN, either regular or limited slip, and the 9" was standard on them 49 States 5.8L (351) HO V-8 - AUTOMATIC, with the 9" being optional on the regular diff and standard on the limited slip diff High Altitude 5.0L (302) EFI V-8 - 4 SPD MAN, with the 9" standard on both regular and limited slip diffs High Altitude 5.8L (351) HO V-8 - AUTOMATIC, with the 9" standard on both regular and limited slip diffs 4x4: 49 States 4.9L (300) I-6 - 4 SPD MAN 0/D: 9" optional on both regular and limited slip diffs 49 States 4.9L (300) I-6 - 4 SPD MAN: 9" optional on both regular and limited slip diffs 49 States 4.9L (300) I-6 - AUTOMATIC: 9" optional on regular diffs and standard on limited slip 49 States 5.0L (302) EFI V-8 - 4 SPD MAN 0/D: 9" standard on both diffs 49 States 5.0L (302) EFI V-8 - 4 SPD MAN: 9" standard on both diffs 49 States 5.8L (351) HO V-8 - AUTOMATIC: 9" standard on both diffs California 4.9L (300) I-6 - 4 SPD MAN 0/D: 9" standard on both diffs California 4.9L (300) I-6 - 4 SPD MAN: 9" standard on both diffs, except that the SuperCab got the 8.8" diff in both cases California 4.9L (300) I-6 - AUTOMATIC: 9" standard on both diffs California High Altitude 4.9L (300) I-6 - 4 SPD MAN 0/D: 9" standard on both diffs High Altitude 4.9L (300) I-6 - 4 SPD MAN: 9" standard on both diffs, except that the SuperCab got the 8.8" diff in both cases High Altitude 4.9L (300) I-6 - AUTOMATIC: 9" standard on both diffs High Altitude 5.0L (302) EFI V-8 - 4 SPD MAN 0/D: 9" standard on both diffs High Altitude (302) EFI V-8 - 4 SPD MAN: 9" standard on both diffs High Altitude (351) HO V-8 - AUTOMATIC: 9" standard on both diffs Link to comment Share on other sites More sharing options...

myrl883 Posted February 12, 2020 Share Posted February 12, 2020 I've only found the partial VIN that is stamped on the top of the frame roughly above the passenger's feet on the trucks I've had apart. The difference whether trucks got a 8.8 or a 9" was strictly determined by gear ratios ordered and GVW of the truck. By the '85 model year, most all trucks had 8.8s. I was shocked to see a 9" in one of my son's trucks, which is a 1986 F150 built 09/86 in Canada. Link to comment Share on other sites More sharing options...
