I appreciate the info.... but that brings me to the next questions.... Chevrolet T series? I know what the GMT-8000 and the GMT-9000 is but thats just the classic versus the NBS......

 

This one is slightly outdated, but heres a semi comprehensive breakdown

In the past, most platforms were given a letter designation. These not only referenced their relative size, but their drivetrain as well.

These still show up in VIN codes to this date.

C: 2wd Fullsize pickups/SUV’s
K: 4wd full-size pickups/SUV’s
S: 2wd compact pickups/SUV’s
T: 4wd compact pickups/SUV’s
E: 2wd Electric S10 (Chevrolet Only)
G: 2wd full-size van
H: AWD full-size van (GMT 610 only)
M: 2wd mid-size van
L: AWD mid-size van
U: FWD minivan/SUV’s
V: AWD minivan/SUV’s
B: Medium Duty Bus Chassis/Cowl Conventional
C: Medium Duty Conventional
T: Medium Duty Tilt-Cab
W: Light/Medium Duty Tilt Cab (Partially/Completely built by Isuzu)
P: Forward Control Chassis (Sold to Workhorse/UCBC in 1999)
R: 2WD Fullsize Truck *
V: 4WD Fullsize Truck *

* In 1988, GM launched it's all new line of GMT 400 C/K pickups, but certain variants - namely the 2-and-4 door utilities, and crew cab pickups - were not yet available. Thus, the prior C/K series' lifespan was continued as a stop-gap measure, and their chassis designations changed to R and V, respectively. This ended in 1991 when their 400-based replacements were launched.

Within the last decade, GM has made the switch from letter-based codes, to those with numbers - and even more recently, Greek letters. While GMX ### signifies a car-based platform, here are the relevant GMT truck platforms.
