Found a blazer, What should I look for and how much to offer???

[bagged91]

I found a 69 or 70 4wd K5 Chevy Blazer yesterday. It appears to be semi original, partly unmolested.

It still has the original paint(blue) with the double wall top. I did see a small crack at the rear corner on it but looked fixable. Liftgate & all glass looked OK. Tailgate is rotted. 1/4's didn't look too bad but they do have some rust. Rockers have small pencil eraser sized holes all over them. Doors were fixable but have some holes. Fenders are crap as well as the grille. Has a small nickel sized hole over windshield above drivers head but bottom of windshield looked ok.

Truck has BENCH seat in front which appears to be a pickup seat as the upholstery doesn't go all the way to bottom. Didn't Blazers come with buckets??? No rear seat and rear floor appears to be rusty. Truck is not a CST, has no A/C, no Tach or tilt. It is a 4spd, not sure on motor or running condition. Has cheapy 6 lug white wagon wheels which are RUSTY with one flat tire, no suspension lift. The rear lug nuts & studs appear to have rotted themselves together(can't see the edges of the lugs or threads on studs). Truck was last inspected like 4 years ago and last registered 3 years ago.

What else should I look for on these. I don't know too much about them... How much should I offer. Oh, it also has an old plow on it...

I have an 8 lug Dana PowerLok rear in my 72 Burb(coil spring). If I get this K5, I would want to put the Dana in it. I should just have to weld on axle pads right??? What can I swap the front rear for(cheaply) to give me 8 lugs with DISC BRAKES. I would want to do a moderate suspension lift to put a set of 35X12.50x15's on it. Not interested in offroading it, just want a BADA$$ lookin truck....On a budget...

Thanks!
