Are you asking about just Chevrolets, or G.M.C.s as well? | | | | | Joined: Jan 2000 Posts: 2,074 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 2,074 | Per my OLD parts book all trucks are the same but does not list all the cab over models. If you can get the casting numbers I could look them up though.

Thanks for the info. Chevy to Chevy. I was going to use a COE as a doner tho so I wonder what could possibly be different? I'll see if I can get castings. I can on my COE, but maybe not my friends that needs replaced for some time. Thanks again | | |
