I still have the mustang I got when i was 18 but it's an 87GT. Do I get extra points for picking up a matching 87gt convertible or still having my Dad's old bronco that I drove the day I got my license?
As for that nova... Aren't those years subframe cars? re-enforce it, add a cross member and ladder bars with coil overs. You don't have to tub it out for that stuff and you'll get more room for tire and better traction.
