IMHO the fastback looks a lot better than the regular sedan. In my case we got rid of the OEM wheels, (one wasn't right for the car anyway I still have them) in the rear we have 215/65/R15 tires (26 inch ) on 15x7 Montie Carlo SS wheels and 215/70/R14 tires on 14X6 S10 wheels. (both wheels look the same style wise) sand blasted by me and painted by my 11year old grandson. On the 75-79 novas the front track is wider than the rear by 1 inch. Both wheels fit in the center of the wheel well and the front and rear are closer to having the same track. The rest of the drivetrain is a 8.50 open axle with a 2.73 ratio and a stock (for now) TH 350. Wasn't the 3.55 gears that you put in for Powerglide cars? Jay
