71-72 GMC SWB big block value

[beaterC10]

This past weekend at the swap meet a guy asked if I would be interested in buying 3-4 swb project trucks. I am a 73 -87 guy so I don't know what they might be worth. I don't have pictures and I haven't seen the trucks. I am just looking for a typical value range. I know they are projects and I have seen enough midwestern trucks to identify junk when I see it. Can anyone give me some guidance?

The total package is supposed to consist of 3 complete swb trucks plus one rolling chassis and bed. I believe there are two short wide beds and two step beds and some new sheetmetal I am assuming is repop.

The truck I am most interested in is a 71 or 72 GMC short wide bed that is supposed to be an original big block a/c truck. The original engine and trans are gone, supposedly the rest of the big block hardware is present. From the pictures it looks like a fairly complete project that needs paint and I am assuming typical bodywork to the cab. Any idea of what a range of values on this truck might be?

The bare chassis is a rolling drum brake coil spring swb that has new suspension bushings and wear items and has been powdercoated. The guy volunteered that the trucks belong to a friend who decided to go racing after buying the trucks for a project. He was originally asking $3500 for the lot which dropped to $3000 and sounds like can go lower. Can anyone give me a range what this pile o parts is worth? Thanks.
