what size engine does it have? if it is an original 225/3 speed manual car, then i would say 12-1500. if it is an original 318 or 360/4 speed then it could be upwards of 25-3000 or better, which means it could have an 8 3/4, big bolt pattern and disc brakes as well. we need to know what drivetrain it has. drivetrain dictates all the heavier duty equipment and "the good stuff" .look through the windshield, bottom drivers side,you will see the VIN number, write it down and post it OR remember the 5th digit, and post it, that will tell us so much more. the question really is ,what is it worth to you?
