Hi Guys,

I am having a situation with my driveline. After removing my 428 and installing a 427 SO. I got a driveline vibration.

Under the car looking rearward the tranny seems lined up pretty well with the frame rails. As you look further rearward the Salisbury (in a Contemporary) sits slightly off-set to the left, It appears to be designed this way with the main part of the pumpkin centered, but the pinion shaft about a half inch to the passanger side. It seems wierd but It is, I assume normal, as the car has never been damaged, the rear wheels line up, tires are equal distance from the fenders, etc.

In any case there is now (since putting in the side oiler) a pronounced jog in the driveshaft left to right between the tail shaft and the pinion flange. I had a shop look at it and he was baffled (not a cobra or component car shop).

My question is I think for Contemporary owners mostly, but anyone really, Does a left to right offset create a a vibration like an up / down pinion offset does?

It seems like a no brainer. Maybe my shop guy was apprehensive about working on a "kit car" without a factory spec. to work from or maybe he was still wigged out about going 0-100 in under 10 seconds.

In any case he noted a small difference in the up down pinion angle and suggested I start there.

Thanks in advance,
