GMC never adopted the cat eye front end the the Chevy's did in 03 and up. I would wan't the newest truck I could get of that vintage. As stated earlier in the this thread the canbus protocol changed in the middle of those model years as well. If you like the 01-02 chevy front end, find a GMC truck up to the 07 model year.

The 8,600 GVW and above SUV, Fullsize Vans, and Pickups got GM CAN Buss on 2004 and later chassis.
The 1/2 ton Silverado and Sierra got GM CAN Buss in 2006.

Continuing production of the prior chassis after the new one is being sold is nothing new for GM. The T400 continued for two or three years after sales of the T800 began. The RV squarebodies continued being produced for four after GMT400 sales began.

RTFM... GM Parts Books, GM Schematics, GM service manuals, and GM training materials...Please include at least the year and model in your threads. It'll be easier to answer your questions.
