The Stovebolt Site Forums The Shop Area Paint and Body Shop Body mounting help

Ok. I have a 47 frame that used the single center mount for the rear of the cab. I have a 52 cab with the shackles that is going on this frame so I will need to drill the frame for the shackles

In the assembly manual, section 1 sheet 3.12 states the following:

Shim used to maintain .76 dimension between floor panel and top of frame.

So do they literally mean the floor pan or the floor support where the shackles mount? The floor support is 3/4 of an inch all by itself so .76 to the floor pan puts the floor support basically right on the frame.

Anyone have any advice here?

Now this is interesting. The shop manual says the clearance between the support and the frame.

Now if it’s the support.... the bottom of the support? The top of the support?

Crawl under someone's truck with a tape measure.

If it were me, I'd just mock it up until it looked right.

The .760 -.820 is from the bottom of the support. I've attached a picture from my 1954 3604. Its difficult to tell due to the angle I took the picture but the distance is .775 on mine as I rebuilt the rear shackles and replaced the front mount rubber and bolts.

But I don’t want to throw off all the front sheet metal. I believe the clearances are important for everything lining up.

Dusty, thanks for the picture. It’s very helpful. Can get a 3/4 board in there it looks like and shim to get it right

Dusty53, That will do it. LMC sent me a bunch of round and square rubber shims and said good luck Ed. I think it is a matter of who was on the assembly line. LMC sent them free because I have used them almost exclusively for about 42 years. Doc
