I have a Factory correct, I.E. part number correct, Six Pack/ 6BBL 727 Torqueflight transmission, that is date coded correct for the SPD of my car.

It has NO VIN stamped on the pad, but does have the correct Six Pack/6BBL PK Part numbers for a 6BBL 727.

The question I have is about the tail shaft. I was told by the guy that is rebuilding the 6BBL transmission that the tail shaft (which I believe to be original to this specific transmission) is from a C-body because it has "studs" mounted in it for the transmission mount. And the studs appear to be original. And my rebuilder says quote, "B, and E bodies did not come with studs for the transmission mount, they had bolts to mount". He has years of experience with only MoPar 727 transmissions.

My question is this: Did E and B body MoPar 6BBl transmission tail shaft mounts have bolts or studs? I have looked into this with owners and others with original 6BBL transmissions and this does seem to be true.

If so, my original Six Pack 727 seems to have come from a C-body......

Any thoughts or comments are appreciated.
