Cab Mount Replacements - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I should probably replace the 45 year old cab and radiator support mounts. Going thru the Brothers Trucks catalog it lists cab mounts for 1/2 only. Is it a different mount for 3/4 ton? The only reason I'm going to them is that they are local and I can save on shipping.

Yes the rear cab mounts are longer than 1/2 ton. I found a set of 3/4-1 ton- 4x4 mounts.

I believe the 3/4 and 1 ton 2wd mounts are the same as all 4x4 mounts if that helps your search at all.

Yes, it does. Thanks for the help Looks like the Car and Truck Shop in Orange Calif has them. Looks like I have my next project lined up. Wonder how hard they will be to change. Unlike a lot of trucks I hear about, the cab corners on mine are in great shape.

The only rust problems I had was due to my dad not making sure the drains at the doors, rocker panels and front lower cowl areas were clear of debris.

Do one side at a time and you will be fine. Loosen the other side just enough to clear you of any tie ups with the mounting hardware.
In doing one side at a time it insures the sheet metal stays lined up. Now all of that is a mute point[means to not talk about it][not moot witch implies it doesn't matter]if you have the truck all apart and are doing off the frame type work to the truck in this case you would need to measure before some assembly. Say the distance from rocker to frame and like places on the opposite sides. Once everything measures the same distance then you can line up the front sheet metal using a X-out method. Jim
