88 CHEVY G20 VAN DOOR ?

I have a 1988 Chevy G20 van - 1/2 ton - 305 v8/automatic. My wing windows are shot on the front driver & passenger door.
I have a junk yard near by that I want to get some good used doors but I do not know what years interchange.

What years do the front doors interchange ?

if you phone the yard they should be able to tell you. i think is like 88 to 95 or 96 .

The junk yard is " from the old school " - that means an old man with tons of cars, trucks, & vans near the road. He does not have a phone & his memory is not to great either . But he has a bunch of these vans.

I do not know too much about Chevys that is why I am asking you guys on the forums. Thanks & I hope the van gurus will start posting.

anything from 95 down should fit gmc or chevy  my 93 chev has 1 door from a 88 and one from a 94 or 95
