I've got all the frame dimensions for a 72 Nova here in my 72 Fisher body manual. What dimensions do you need? Send me a PM with your E-mail address and I can scan it and E-mail it to you. I don't think I can legally post this stuff since it is owned by General motors.
i have a front subframe from a 70 nova. its been sandblasted and chassis blacked...i spent well over 3 days cleaning and painting. but i ended up buying a aftermarket frame. i would let this go for 100.00 if you pick up or if you pay shipping i would ship for 50 extra (for pakaging) plus shipping fees.
