i just put a gn rear in my regal and i need a driveshaft that will work with the TH350 and the 8.5 rear. i was told a stock gn driveshaft will work perfectly. anyone??? i'm located in philly so i'm trying to pick one up asap. thanks.
yes the stock one should fit just fine. I changed over a 79 trans am from 350 to 200r4 and it still worked fine. Your just going the other way. Daniel Ray
