It's a '77 1 ton 4x4 Crew Cab. Dana 60 front, 14 bolt rear, 4.56 gears, 454 with an RV cam, Edelbrock intake/carb, 60-70,000 miles on the motor, brand new TH400 tranny, 203 T-case with part time kit, 33" tires, chrome wheels, fair body/straight, (little rust). Only problem is that it sounds like the flexplate is cracked (the guy thinks its the tranny itself). Advertised in the local paper for $2000. Should I jump on it?
