Well Cranky, I'll put it in perspective from my view, I paid 75 dollars for a set of the cast weights to put on my 68 Suburban, I drove 75 miles and paid 50 dollars for a 68 Suburban 12 POS with no motor that had the original grill, grill wires and side panel to put on mine, I think you did good for 80 dollars, they are getting harder and harder to find in Georgia, I had an SS16 with no motor or hood, and no engine with a complete 3 point hitch given to me to haul off, I try to put my 2 together with what I can find and grab, I think you did good!!!!!
I rarely turn down cheap tractors and especially not ones with weights - I drove 3 hours round trip to get a machine with 2 sets of weights once- traded a handheld blower for it
