I have a 52 panel and used the mounts that I bought from JimCarter but the mounts were made by Chassis Engineering. Loved the way they work but I believe your GMC is a little "longer" in the front....in other words the measurements from the front cross member would be different????

If you can look at my photobucket there are a few pictures.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
