I know what posts you're referring to. Thanks for the reminder. I'll be sure to swing by and read up on it again.

I do think I have a good idea as to what's causing my vibrations. When I changed rear springs, this raised my car and pulled the drive shaft out of the transmission more. Combine that with the play there is in the slip yoke and I think that's why I picked up this vibration after the rear suspension was done. I'm not leaving the rear end raised up like it is so I guess I'll be swapping the springs out sooner than later to get the rear back down to where it was with the stocks springs.

I'd still like to figure out if my engine is pointing straight back or not or if it even matters.

Thanks
