U Bolts that Fasten CMP Rear Body
 

Afternoon Chaps,

I'm sure this has been discussed before and there are many threads that inadvertently cover this topic.

I'm looking for the exact location of where the U Bolts that attach the rear body to the truck are fastened along the chassis of an F15 (2WD) Cab 13.

I'm guessing it may depend on the body type. The one I have is a 2C1 all steel Canadian body.

Many thanks.

There is a sketch for that somewhere on the forum, will try to find it

Very helpful
 

Thanks very much Hanno
:thup:

Depending on whether there were production variations and whether Ford and Chevrolet for some reason had different mounting of 2C1 bodies, Bob Carriere's Cab 11 (with some Cab 12 features added) which has a later body attached until the 2B1 is done may provide answers. Jordan Baker also posted on the installation of the wooden blocks designed to prevent crushing of the frame rails by the body mounting bolts. May also show bolt location - don't recall.

The longitudinal sills (steel) that hold the wooden fillers over the chassis rails are wider than the chassis rails. As a result, the inner leg of the bolt passes through holes in the sill and filler. Assuming your truck still has the holes, you should be able to see/feel them (depending on whether the body is on or off the frame.
Drawings prepared by Ted Gil of the 2J1 body give these holes as being 11/16" diameter. The sills are drilled both left and right on the top face to allow the same part to be used for both left and right sills (only the inboard hole is used on each sill). Overall length of the 2J1 sills is given as 6'-6.25". The front u-bolt holes are given as 3-5/16" from the forward end of the sill. The rear u-bolt holes are given as 13-3/16" from the rear of the sill. There are also holes drilled at 7-1/8" and 9 inches ahead of the rear u-bolt holes (purpose of these not stated).

Naturally, you should confirm this makes sense for your truck before doing any fabrication.... I presume you are like me and hate wasting time doing a job several times and wasting material.

It’s not about 15 cwts, though

I can take photos and measurements on my F15A if you want?
