Hey all. Just bought a 1990 k3500. I'm sure someone knows what years of back bumpers I can use on this truck.
Thanks in advance

The truck in the picture is a 1980 not 1990. the truck in the picture the bumpers went from 1973 to 1987. then the gmt 400 bumpers went from 1988 to 1998, and some until 2000.

I believe the crew cabs were square bodies until 1990, so he may be right on the year. I could be wrong, happens sometimes. Lol

Until 91 crew cabs, blazers and suburbans. 80-91 square body bumpers would work. Brackets slightly different on 73-80 but would work as well if correct brackets used. Does it have the factory vss equipped np205? 91 recieved them, and 90 should have but some seem to be cable driven speedo

Absolutely not an 80, the front marker is horizontal. 81 is the first year of that.
Crew cabs are squares through 1991. Blazers and Burbs as well.

The 91 crew cluster is the only vss compatible square cluster, but it's entirely possible that some late m/y 90's had them as well. I imagine the same is true for the transfer cases.

@Bradster68 as stated any square bumper will work with the right brackets, I'm also sure that you can fab stiff to make 400 and 800 bumpers work as well.

Suburbans got vss in 90, while k3500 seem to have been not so much until either late 90 or 91 only. Guessing GM was really trying to avoid adapting np205 for it but then gave up.

My experience is with a C3500 (technically an R3500) not a K(V) which obviously didn't have a transfer case. I was under the impression that the gauges from 91 squares were the only ones that work with an LS swap, if the Burbs got vss in 90, they would as well presumably. Good to know.

K3500 were squares in 1990. Not sure when they stopped, I'm very new to these trucks and body styles,but I know that in 88 the 1500s and the 2500s received body style changes but 90s didn't.

Not sure what np205 is? I'm a newb when it comes to these square body years and compatibility
