MA70 is any Supra with a 7MGE / 7MGTE. JZA70 is just the 1JZ-GTE MKIII ( Only in Japan and other non-NA ). GA70 was a 2.0 liter twin turbo narrow body Supra ( Only in Japan or other non-NAmerica ).
For a 2JZ swap your best bet is a 89.5-92. Crossmember / Motor mounts are different as well as the wiring on pre-89.5's then JZA70's. You can get adapter brackets from BIC on here though for pre-89's.
