GM Powerglide to MOPAR adapter plate.

I am in need of a adapter plate to use a GM Turbo or Powerglide behind
my 474 B engine. I just bought an engine with the gm flex plate and crank
adapter on it but need the plate that goes with it. Its TCI and its a combo
adapter plate and rear motor plate. Anyone know of one availble:bootysha:

Thanks,
