Pure Magnum swap

:banghead:WHOA WTF? I just removed the original flex plate from the magnum to measure which hole had to be elongated. I put it on the torque converter and it ain't even close to the right size! See pics.
This is supposed to be a standard 727 with an unidentified torque converter (see pics) what the hell can I do with this?

Only one bolt is screwed in and look how far off center it is! The others don't even reach the edge of the flex plate:angry5:
