No, although sometimes just because nothing was changed doesn't mean it was alright before you started... I took some measurements. I found the tailshaft of my toploader to be within 3/16" of the 18 1/4" distance between the frame rails of the Contemporary.

The interesting thing is, the pinion flange is indeed offset. it is 8 3/8" off the passenger side frame rail. That gives a total offset of 1 1/2" off centerline. I guess this is normal. Who knew. I never paid much attention. I took the driveshaft out and it doesn't look like it's thrown a weight but it seems like an amature put it together. The face of the yoke isn't straight. It looks like it was hacked off with a hand saw. One U joint seems to have a point at wich it sticks as I turn it by hand. In either case It seems suspect and needs attention.

I suspect somehow changing the orientation of the engine with the transmission, despite it being correct has changed the dynamics or the way the driveline "feels" and the harmonic characterists it has despite not actually being worked on, or changed during the engine swap.

Thanks for the input and for everyone that looked at the thread, problems like this are frustrating and take patients to solve. I will update this thread as soon as I get my driveshaft back from Dirveline Speciality Service in Sacramento, CA early next week. They promise a 24 hour turn around and are open on Saturday.

I would like to say the guy who was reluctant to alter my transmission orientation was probably right, at least he was from a distance to centerline perspective. Everything seems like it is where it should be. So thanks Gear One in Vacaville, Ca and Jim in particular. He took the time to put my car on his rack and spent a 1/2 hour talking me out of changing the position of my toploader. NO Charge.

I'll let you know how it works out,
