Mike, did you happen to see the two larger bolts, also known as dowel
bolts, when you bolted the transmission to the engine?  I believe they
are special bolts that are approximately 3/8 inch diameter, and they go
in the 2 and 8 oclock positions looking from the rear.  If you don't
have them it is possible that your input shaft is slightly off center
with respect to the pilot bearing so it wobbles and can cause judder.
This happened to me on my recent rebuild, now the judder is gone since I
didn't realize that the thru holes are slightly larger than the rest in
these two locations.  So if those bolts are not present, it should be
possible to remove those and insert the right ones.  Perhaps they got
used as starter bolts?  In any case, I believe they are not simply 3/8
inch bolts and are slightly larger than 3/8, otherwise you may be able
to get them from the big 3 but I don't know if they are offering real
dowel bolts or simply 3/8 inch bolts.

I just finished a engine rebuild with the engine out of the car. after
getting everything back together the engine runs good but I have a real
bad clutch judder. When I take off the whole car shakes. I did not have
this before. what will I have to do to fix the clutch judder? Appreciate
any comments and thoughts on the shaking car problem.

Thanks
