HELP thump during turns after transmission swap

[1968_Charger]

i just finished putting in a new sb 727. everything seems good while driving, but when i take a turn something under the car feels like its hitting the bottom of the car. it only happens while im turning and it sounds like its coming from the front seats back. i put new u joints in the driveshaft when i had it out also. ive looked under the car but i dont see anything odd
any ideas?

did you properly tighten the transmission mount?

exactly what I was thinking as soon as I saw the subject.

i tightened it but it was pretty wore out. think that could be it? never did it before the swap so i figured it was good enough to reuse

I think you are on to something.  Dive under and see if you can move the tranny by hand.  A good cheap start regardless since you mentioned it was worn.
