Hi,
I just bought a 2000 Chevy K3500 Crew Cab Long Bed.with a 5.7L (350).



It was lacking three items I desired but the price was correct and I can add the desired items if and when I want. 1) 7.4L (454); 2) Power locks; 3) Power windows

In searching the web for info on this truck I came across a range of truck model years that parts will fit my truck (99-02), some acronyms (OBS, NBS, NNBS), transmissions (4L80E, 700R), rear axle ratios (4.10, 3.73) and GM truck platforms (GMT400, GMT800).

Given I have a 2000 I believed my truck was a NBS on a GMT800 frame wit a 4L80E transmission and unknown rear axle ratio (believe it is a 4.10 due to engine size). However, recently I was told it is not as I believed because Chevy did not switch the 2000 K3500 model to the new body style and frame. So, can any of you tell me what my truck is?

 

It's a GMT400

 

yep OBS. Mine is a 99 K3500 but I have to use 98 for parts for it since your truck the K3500 went up through 00
