22re to 22r ???

I have a 1991 pickup reg cab 2wd with auto trans. I have had many problems with the electriconics first the ECU went out now the mass flow air sensor is not working. When I removed the plug from the mass air flow sensor I damaged it the plug only comes with the whole harness that runs from the engine compartment to the ECU box in the cab. The wire harness is around $800.00 and the MFS is about $300.00. My question is what do I need to convert this to a carb set up. I live in Hawaii and we don't have any emmission checks. I would really like to get rid of as much electronics and emmission stuff as possible. Can this be done with out much modifications?

 

ive heard a couple people went back...don't really know much about it tho...just heard about it
