The Stovebolt Site Forums The Shop Area Paint and Body Shop Cab height/space

I am attempting to build a 47 3600 chevy truck and I am a little over my head. The truck was in pieces when I got it. I don't have the center shackle setup for the rear of the cab and I fabricating my own mounts. My question is: what is the rear of the cab height from the frame? I am assuming it will make a difference with the front sheet metal alignment and the bed appearance.

Thanks,
Chuck

Is it a 3600 cab on a 3600 frame? The only reason I ask is my in a million pieces project I had a 3100 frame with a 6400 cab and shackles. I researched all over to resolve it. Finally loosely put the front end, running boards and bed on to see where the holes needed to be on the frame. In your case you would benefit with at least one stock to duplicate a pair of rigid mounts like others have done. Maybe someone that has done that can chime in with measurements.

Chuck, Since it's a 1947, the only place I could find a possible reference to your measurement comes from the 1947 Chevy Truck Data PDF from the GM Heritage Center. The pic below shows the "top of cab floor" to "top of frame" measurement to be 1-7/8" from what I can see.

If you measure your "top of floor" to "bottom rear edge of the cab" and take that away from the 1-7/8" measurement, that should give you the distance between the top of the frame and bottom of the rear cab edge that you are looking for. Hope this is clearer than mud and helpful???

Thanks for the replies. I believe it is a 3600 on the correct frame data plate and measurements lead me in that direction. I will probably take Gdads advice on the spacing and build some mounts from that distance.

Chuck, In doing a little more resource searching, I found the below pictures extracted from this other 1947 Chevy Truck Resource that are a little clearer and also show the earlier 1947-48 AD cab mount system. Offered in the hope it may help you with fabricating yours. The resource document may have other info to also help with other aspects on your truck.

What I would do is get the later dual rear shackle setup and use that. The reinforcements for the cab floor are available aftermarket for the later cabs and I'm sure someone has a set of rear cab shackles laying around they'd be willing to sell/gift you. They could be fabricated from measurements if push came to shove, but there are enough around to avoid having to do that.When I set my cab on the frame, I used a couple of pieces of 1x3 board and it worked our exactly for the 3/4" distance from top of frame to cab floor. I'm sure someone would be willing to measure bolt hole locations for you.
