I’ve always seen these referenced as Tremec transmissions... 🤷‍♂️ I don’t think they are related in any way to Clark, but I may be way wrong. Tremec

I've always felt that the trans that is on Gary's list (Clark) has to be a misprint..Unless back in the day they did refer to the various rug 170's as clarks. They may have come with a Clark, but this particular 4spd OD I believe must be a RUG 170 variant If anyone actually has found a Clark 4 or 5 speed in one these trucks of our vintage please speak up and share the bell housing and clutch arrangement with us. These are rare installs in our trucks I believe. here is a great discussion on Clark 5 speeds at another site. https://fordsix.com/viewtopic.php?f=2&t=79566&sid=f2d2727777286dee16e099b18d7e83ae I concur with 1986f150six, after having owned two of these I would use it for sure..Good luck

I think he may be looking for the mount of this version..My Bronco has one I'll try to look at it today.

Interesting combination

I built my Bronco with '95 4.9L (EFI 300ci), NP435, BW1356, Ford 8.8" 3.08 open, ~32" LT285/75R16. I can set the cruise above 100mph without going over 3500RPM. Seems as though you have a great combo. When I’m pulling my boat especially on the “blue-line-highways” through the various mountains of the west, I get along very well with 3.50’s in the back end. In all practicality, a direct r/a is a very good comprimise for a 86 Ford “brick” that I’m driving, especially since I use a 31” tire. I’m going to talk myself out of OD if I think much about it.. 😎 To all whove responded, thank for for your patience. To those of you who have contacted me and are considering making a trans combo available, I'll visit with you about that if you are still interested but.. I've decided to keep my old school NP435 for now and will probably rebuild a spare so I can swap it sometime in the future while doing some clutch work. While pulling my boat complete with all of the camping gear, I can pull any 6% grade at about 45 mph now with the current tires and 3.50 gears. This is while being in 4th gear, and it seems happy pulling it. I can do 55-60 comfortably and after all it IS a Bronco so as long as I keep it I'll most likely leave it like it is w/o OD Happy motoring all..

Here's another link about a Ford powered RV very famous. https://www.offroadxtreme.com/news/the-condor-rv-that-beat-the-1969-baja-1000/

I was Digging up old past articles I had bookmarked and found this custom F350 300-6 powered with a Clark 5speed OD. https://www.ford-trucks.com/forums/1210319-overdrive-clark-five-speed-information-compiliation.html interesting history Evidentley 1966 was a very good year for Ford Transmission offerings.

One of the reasons I have an NP435 I once had the feeling that "real" transmissions were cast iron, and should be shifted manually. I still prefer them mainly for my life experience with cars for many years. Also when I worked for someone else I drove one of these for many miles. winter of "75" which btw still have a pedal through the floor generally I am interested in seeing an SROD version all complete with the 4WD trim. One of my vans had a 2WD srod and it shifted great. The little tower worries me a little bit, Ill look at it. The tailshaft housing mounts worry me a little bit, making me want a cast iron version of possible but it may not exist. the weak spot seems to be in the tcase adapter trans mount. I like your combo with the t19. If I had 3.00 R/A gears i wouldnt consider OD at all. Actually my 3.5 RA is fine and lets me drive in town w/o even downshift in traffic most of the time. The 300 as you know can idle along and then start pulling from idle right on up...lazy actually. My choice is to have a spare trans complete if I can find it. I'm not on fire about it though so wisdom and patience is going to be part of it.... BTW one of my favorite vehicles owned in the past was a 66 intl travelall v-8 with a Clark 5spd OD.

great perspective ..thanks for input I'm in the data gathering stage, and parts for a swap. I want to confer with some people who rebuild various versions of trhe Tremecs including those versions for Jeeps as well. I would love to find an earlier SMOD cast iron version if it was actaully built in 4WD as Blue Oval stated, but I will collect any version that is complete and in good working order that came in a Ford originally. Eliminating hydraulics for me is a choice of eliminating a parts cource I'm not in control of and prefering not using an integral bell in my install. I appreciate the input of an extra rod when in the "outback" or extended trips..it doesn't take up much room for sure. Good day all..

I appreciate this info for sure. I’ve thought about the 3550 as well as the bigger one. Part of my reason for the lighter, smaller SMOD version If it can be found is my interest in the toploader trans itself. I’ve owned two in two different e150s. I Had the big 6 speed NV in my Dodge truck as well. Before I pull this NP435 out to do some work, I would like to replace it with a spare something without having the vehicle down for a big changeover. Also a trans that weighs less than 100 lbs appeals to me as I have limited shop equipment available being retired... Thanks for your response. Best wishes Ken.

Ok Gary, I just wanted to offer.. at this point I have a complete set of manual stuff to use in the future if it’s ever needed. As I move on I may have a line on some Hd metal bushings that could be used as well. If I come up with that solution, I’ll let you know. Good to be tuch...bless you and yours brother..

Thanks for the comments on this topic all. I realize Ford's early design of the clutch hasn't been one that many have chosen to praise for mainly wear reasons, and of course the wish for a juice clutch system. Thanks Gary for your donation of the bushing repair you did on the clutch parts set you sent me. If for any reason you would like to have it back I'd be glad to send it...great work. Since I plan to keep this system operative as long as I keep this truck and especially if I use a toploader version of trans, I will in time this year modify my clutch parts to utilize a heim bushing system most likely. Nowdays you can buy just about any type of joint parts. I actually had to build a heim tie-rod for my boat when I swapped motors...very cheap.... Anyway, I'm on ther search for a toploader OD trans (preferably cast iron), and the necessary 4WD shift linkage to utilize it. If any members here feel the need to get rid of any of that old outdated stuff, I'm on the left coast and I can afford shipping....thanks all. Enjoy what you enjoy..stay bandaid free if at all possible.
