I bought what I thought were cab mounts from Dorman 924-010 which they claim are good for hundreds of GM vehicles. Because I am a restorer I check everything. Bottom line they are only front radiator supports. They will work on your trucks if you replace all 6 as they are smaller in dia. and appox 3/4" less tall. The factory GM is 15567810 for upper and 15529851 for lower rubbers only. I made mine work but the drivers side is 3/4 lower than passenger side. I will most likely make a spacer from rubber. What is everyone using as replacements since they are all NLA? Tkx Jim

 

Only place I can think of that might carry them is a local shop in my area. Here’s their website - I haven’t been there in years so I’m not sure what their post-covid strategy is but I’m betting they’ll ship to you.

The Body Parts Store - https://bodypartsstore.com

Otherwise, I suspect you’ll have to change them all to keep the cab truly level and comfortable to ride in.

There are several aftermarket options if you’re willing to change to poly mounts.

Just Google “Chevy pickup cab mounts” for several options.

 

Gumby22 I have searched for days under every conceivable name. The site you suggested now only sells paint finishing products. I may just cut a 3/4" x4 dia piece of rubber and shim it as other rubbers and mounts are fine. Tkx

 

I’m wondering if the website is only promoting the shop side - the counter sales side always seemed to be a minor part of the business. But like I said - haven’t been there in years and it’s possible they decided to eliminate counter sales altogether.

Good luck - I hope you get it figured out.

 

I had an extra set of the Dorman rubbers. Today I removed the side step and 2 drivers side bolts and rear Rubber. I cut appox 3/4" off the spare ,inserted it at the too and reinstalled it all. Pic shows cab to box line off about an 1/8" instead of the 3/4" it was. The mount had rusted the hole larger than the smaller Dorman Rubber so I cut out 1/4" aluminum plate 4" dia with a 2.75 center hole fir the rubber and now all is well. Though yesterday I installed a new turn signal spring too another 15 min. Job. Lol
