question on buckets and blazer tops

[chevy2racr]

ok, I was at a local guys "shop" and junk area today and there was one blazer tub that had been cut up(before he got it) and there were 2 buckets sitting there, black, with scroll pattern on them and the plastic backs, the backs were cracked and upolstry bad, dunno if the frames were straight or not, assume they are fac. I know there are pics around, but would someone make it easier on me and post a pic, dunno what year it was. dunno what he wants for them either, mgiht actually give them to me. then for the tops, what is a double wall top like? how to differentiate from a single? never really looked into this at all, there is a 2nd blazer and I'm gonna guess it was a double wall top, has some cracks, but a little bit of fiberglass work and I think it'd be good. heck, maybe get the whole blazer, dunno if its got a title, who knows how the rocker boxes are, if someone tells me how to examine them I will. ALSO he has a 70 or so GMC SWB 4X4 with 4 spd & 350 I think, the cab is fixable, front clip also prolly fixable. you know how it goes, he has a fleet bed for it, dunno what he'd be askin or anything is someone is interested..
Thanks
