Need help with cab mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everyone,
I am getting ready to put my cab back on my frame this weekend and came into a snag. I know how the mounts go together but I forgot about getting the spacer bushings that go inside the rubber mounts. I don't have any at all so I will just make some here at the shop instead of trying to find some. SOOO the question is: What are the length of the spacers ? I am pretty sure that they are 7/8 round front and back and the front are a 9/16 hole and the backs are 7/16 hole but what is the length.
Also, what is the tq. spec (if any)

Can someone tell me?
Thanks alot

Rears are 0.750 od x 0.563 id x 2.5 lg.
Fronts are 0.875 od x 0.750 x 1.95 lg.

I put about 2 coats of POR15 on mine so the dimentions are only approximate. I tried to round them a little. The fronts are oblong so it is really not that critical. You should be able to find some tubing or pipe that will work. The center hole just needs to provide clearance for the bolt.

The ones I got with my kit measure to be 2.25" long with .75 id and .875 od. the other one is 2 3/16" with a .676 id and .875 od. I am assuming the thicker spacers go with the larger bolts, but could be mistaken. Kit didn't come with instructions.

Hope this helps, Dan

Thanks guys!

I found out that LMC has them and to get them to me would be $45.00
I think I can make some for alot less, YA think, since I work at a machine shop.
