The Stovebolt Site Forums The Shop Area Paint and Body Shop bed mount block sizes

ok heres a good question for you all, okay on the advance design trucks, there are only 6 bolts that keep it connected to the chassis. of the 6 bolts there are four, (the 2 front and the 2 back)that go through these wooden blocks. when i bought my 50 1/2 ton, the guy before me had all ready removed the bed and in the process, lost of threw away the blocks. now im ready to put my bed back on the chassis, after having blasted and painted it. i was wondering if any one knows the measurements (height, width, and depth) of these four blocks? i really dont want to pay chevy duty $12 just for some peices of wood if i can help it. anyone that might be able to help me out id be very grateful. thanks all murdoc.

Good question. I'll measure some on a 52 Chevy 1/2 ton tonight and let you know.

If you are gonna replace the blocks, do yourself a favor & use 1 1/2 " steel square stock instead of wood on the 2 closest to the cab. You can cut the steel in 3" lenghts & drill a hole in the middle for the carriage bolt.
Its a good idea to use the rubber insulators on boths ends of the steel block. If ya use steel you will never have to worry about the wood block drying out & falling off causing the bed to sag & cracking the rear fenders where they mount to the running board. This will also prevent the bed from resting on the running board to bed splash apron. How many of these have we seen that were chewed up by the weight of the bed slappin' around on it.

the block is made from hardwood. [most likely oak ] and it is 2 5/16 " square. The grain runs up and down and the hole is centered.

What Mother said is probably the best advice. My Chevy Duty Replacement blocks are. 1+13/16" high x 2" wide x 2+1/4" Length. The length part rests on the top of the frame, then drill hole down the center of the top. The overall height with thin rubber cushions on either side of the block is 2+1/16". You would not want the blocks any shorter than 1+3/4" high because you will have problems getting on the running board splash aprons. Good luck with your project.
