Depends on the yoke you get on the rearend. There are a variety of yoke lengths on the 9".

I used a stock driveshaft with a conversion u-joint, when I raced stock eliminator with a 200-4R & Moser 9" (not fab 9). It fit fine, raced it 3 years with no problems... But that was in Monte Carlo SS (which originally had 7.5 rear)
