i have a similar "deal" but mine was free also.
went to look at some tri-5 chevy parts, noticed a super clean 79 blazer full size sittin there with no motor, trans, t-case. asked the guy about it, he said he wanted it gone, i joking told him i would take the tri-5 parts(rear window channels, factory a/c vents, backseat frame, lil "crap") if he threw in the blazer...and the guy said ok
so for $100 of customer money i bought the customers parts, and drug home the blazer.
the blazer will be my new "driver/parts chaser", its goin together with a bunch of spare parts that were floating around. this was last week i drug it home, now its sportin 2wd suspension with an altitude adjustment, sittin on 20" wheels, had a TPI 350 sittin under the bench....threw some rings/bearings in it, freshened a T350 to go behind it. waiting on the stand alone TPI harness/computer to show up, then drop in the motor/trans. i think im into it about $900 so far(new tires for the 20" wheels, engine/trans freshening parts, new brake parts....etc) so take 1 free blazer, a bunch of good spare parts, and a couple weeks time, and you get a really cool "driver"
