I am going to look at a 1978 Bronco 351M, C6 tranny w/136K miles. It has a 4" lift with 33 X 12.50 tires. Are there any particular problem areas that I should look for? The owner disclosed that the A/C clutch is not working, tilt steering column is loose, and the right latch is not locking on the tailgate. Thanks in advance for the help.
