Excuse me for assuming but usually when thinking of a 73 Nova build, I'm wondering your gonna' wanna' race it at some point in time. I could be wrong ........... it's been known to happen. If you do want to race it (I'm just sayin') no handles won't pass tech. Track officials want to be able to get you out in the event of an accident. Just thought I would offer the tid-bit of information, even if it's not applicable.
