C10 vs C20 cab and core support frame mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are the C10 and C20 cab and core support frame mount brackets the same?

The round frame pedestal where the cab bushings / core support bushings sit? I would think they would be but I'm not sure.

Thanks

C20 frame mounts sit lower on the frame. For the cab

Just the rear ones.

Also make sure your core support kit is for your year of truck. '67-'68 is different than '69-'72.

The C20 rear mounts on the frame sit lower, that's why the cab bushings are taller. The front frame cab mounts and frame core support mounts are the same.
C10 and C20 cabs are the same.
I have a C20 cab on a C10 frame and everything lines up good.
