The carburetors on '81s were close to worthless because they're so unreliable.

The best choice would be to find an '83 (or '84 -'85) for their fuel system and electronic parts (including wiring harness, sensors, ECM, "the whole nine yards") and swap over. No, it's not easy, but these cars had very troublesome carbs when they were new... let alone now.
