74 Duster, resto mod 6.4 front end rebuild questions

This is the bracket that sometimes Dr Diff has as a A body set up, apparently lifts the booster up higher as designed for a wedge motor
But none in stock or on the horizon I wonder if i could just buy the B body one and modify it?

They use the same mount on the firewall. for the MC. Not sure you wouldn't be able to use the B body one. Cass would probably know.
