Yes my experience with Marti is a lot of the time there is no breakdown of certain sub models numbers for some different options at least on passenger cars anyway. Down the road I may order a deluxe Eppinger report from him. A lot of times it's that Ford didn't really breakdown sub model options either, at least that's the way it is for some of my other vehicles. I did go on the site but didn't see the part needed but will call them when they are opened up in the week. Thanks for that.
I did try to decode my truck on the the sites vin decoder late last night but had problems on certain numbers on my door jamb tag. The condition of my tag is like new but when it comes to finding out what springs and what type of towing class it is, I come up with a blank. I see that info is the same as my owners manual on the towing part but doesn't even list my Z code 400 engine only the 351m. Plus my tag does not actually say springs on the right side near end of tag it is blank but has the 2 letters there that are most likely for front and back which are E and A. My weight is 8650lb. This vehicle really sits high up especially for a 2-wheel drive and there are no mods underneath (all factory) so don't know what class it is. Confused a little on my tag numbers for front and how to read such as Front 1458, 3215lb, and rear 2834, 6250. In that half box on my tag is also FO 175.
FO 435.
