[Jerry8168]

ok heres my problem i have the 2 trucks a 66 chevy long bed and a 66 gmc short bed.. i the gmc has alot of floor rot and i want to keep the chevy logo's and stuff but i need to switch cabs and i was woundering how hard it would be?

changing cabs isn't that difficult.........but aren't the chevy and gmc dashes different???????? hemmit

[Jerry8168]

ya i think it is a little bit im staying with the chevy one

I don't know if there's any differences between the years, but my 70 was a piece of cake, but I removed the front clip which made it easier. It's a good chance to replace the cab and radiator core mounts.

[Jerry8168]

ya i plan on doing that also i am switching the front grill and head lights

I have a 65; changed the cab to a 66. fit right up. The GMC and Chevy dashes are different if my memory is correct. Only thing; you need to keep the original serial number from the old cab & put on the cab you are installing on the frame. Some state motor vehicle departments get very touchy about this. Good luck-----

Now Days Older Cars And Trucks The Dmv Know Most Of The Time The Frame Is Bent Some Time During Its Life You Can Do 2 Things One Gring Off The Old Seril Nb# Offand Restamp It On The Frame Or Cut The Old Plate Off And Cut Yours Off And Reweld It To The Frame I Like The First One Better And How To Do It Make Friends With A Guy That Has A Car Lift The Ones With The Arms It Make Life So Much Easyer

Does Anyone Know If A Chevy Dash Insert Will Fit In A Gmc Dash???????????? I'm Not Sure But I Know They Are Different...............hemmit

Isn't the 64-66 the same with a round guage panel?

I know 60-63 GMC have a single hump dash and C-10 have double hump.

They can be changed, I'm putting a Double Hump in my '64 now.
Looks sweet, but I still need to work the ends.

The GMC dashes '60-'66 are the same, with 1 hump, just the guage clusters were different. Chevy guage cluster will not work in a GMC dash. Any '63-'66 truck cabs are interchangable (1/2 ton) the 3/4 ton rear cab mounts use a different rubber mount.

The '63-'66 GMC frames have leaf spring rear end setups, and chevy's had trailing arms '60-'66. The good thing about having the leaf spring setup in the rear on the GMC's, you can mount just about any rearend right up, and be done.
