I recently put in a Moser 9in and picked up a bad vibration. It looks like my 1LE DS is a little too short and possibly the cause of the new vibration. I'm planning to pick up a N20 shaft from Denny's soon and want to see if anyone knows the common measurements for my setup. Car is a 94 f-body with a 93 M29 manual tranny. I measured what I think the overall length should be and came out with 44 & 7/8th inches. The rear is a Moser 9in with a 1350 on the pinion.
