The wood spacers that support the bed on my 47 half ton are gone and I'm planning to replace the bed wood soon. I really hate the idea of ordering 4 wood blocks with a hole thru them. Any one have know how thick (tall) they need to be?

Not sure if a 47 would be the same, but on my 51 3100, I cut them 2" x 2" x 2-1/8" tall out of scrap pieces of treated 4" x 4" posts. Drilled a 1/2" hole through the center, put a couple coats of back paint on them, and used a piece of gin belt (which was about 3/16" thick) as the rubber spacer. Everything lined up and the bed sits correct.

That sounds like exactly what I was thinking. I'm betting mine is the same thickness.

Thanks!

Mark,

The wood spacers for my 51-3100 are 2 1/8" tall, plus the 1/4"rubber isolator pads between the frame rail and the wooden blocks. I got the bed mount kit from LMC Truck, it included the blocks, isolator pads and hardware. Hope this helps.

Yes it does. Thanks.
Mark
