Yes, but it takes a little bit of work. 70-81 Z-28 and Trans am rears are about 1" wider than the Nova's rear. 82-up are no good!!! I put an 80 Z-28 posi rear with 3:42's in mine. The rear tires get moved out about 1/2" on each side, but you'd never know it from looking (see the pic of my car below). I run 225 60 R 15's with no problem. I have run 245 60 R 15's with no rubbing but they are just a little too close to the wheel lips for comfort. This is what I did for my swap: cut the spring perches off the new rear, center the new rear in the Nova and make sure the pinion angle is at the same angle as the original Nova rear, mark the location of where the new perches have to be welded, make sure to double and triple check your measurements, get a set of Nova perches and weld them on (I recommend getting a professional welder to do this because those axle tubes are pretty thick - I got my brother in law to do this for me because he was a welder at the local shipyards), done deal! Bolt her in and hook up your brake lines etc. Now there is only one other problem I had and that was that the universal in my driveshaft was too small for the bigger rear. You will either have to get the proper driveshaft (one out of a Nova that has an 8.5" rear) that takes the bigger universal joint to fit the bigger rear or you can get a universal joint that has one side with small ends (to fit your driveshaft) and the other side with big ends (to fit the bigger rear). I got one from the local truck parts store. I've been using mine for about 3 years with no problems. Although I recently got the proper driveshaft or at least I hope it's the proper one, I didn't put it in yet to find out. Hope this helps.
