Some 1500 '99s are GMT 400s. The 2500 and 3500 trucks went to 2000, but I bet a few might of made it to be '01s. The 3500 HD trucks went to 2002, and toward the end had 8.1L motors.

Also, the '94s are the first ones to have 3rd brake lights and '94 was also the year the grilles changed.

and mirrors changed in 95. also only 93s had dual tail pipes coming out the back. 97 was the last year of the big metal tail gate banner on chevys,98s resembled GMC tail gate badging styles, 99 and 00ss had chevrolet written out across the whole tail gate again but this time in sticker form. 99+ came with a redesigned air box, and 98+ came with a redesigned charcoal canister. 97 for gmc and 98 for chevy is when the C pillar badge went from square to rounded

This is because the wiring harness is specific to the 95 and the bell housing changed after that.

I could still do a 6.0 swap with the 4l65e and it would fall right into place, I would just have to use the 6.0 harness in a 95 am I correct?

It was only an option for Chevys to have the metal banner on the tailgate, GMCs also could have it.

'88-'91 they had the big GMC letters on the tailgate, some had the metal on the tailgate. '92-'97 had GMCTruck on the lower right corner of the tailgate. And '98 and up just said GMC on the lower right corner of the tailgate.

'88-'91 trucks had a small "EFI" sticker on the tailgate.

'88-'89 moon gauges were slightly different than the '90-'91 moon gauges. The needle gauges were a mid-year '91 model change.

'88-'89 door panels were slightly different than the '90-'94 door panels.
