Alright, i dont know what i was thinking but i guess you also need the computer that is compatible with the maf, and the proper size injectors that are calibrated to whatever mass airflow sensor you are going with.
Here are a few kits that brothers performance sells....
Ford racing parts conversion kit: http://brothersperformance.com/shop/mustang/kt022.html
Pro-M conversion kit: http://brothersperformance.com/shop/mus ... 11115.html
Just the wiring harness alone: http://brothersperformance.com/shop/mus ... omawh.html
IMHO these kits aren't cheap. If you buy the cheaper Pro-M kit you get a 75mm MAF with it. BUT you dont get the injectors like the ford kit has. Again i'd just try to find somebody parting a car out and buy all of this stuff as a package from them. I've seen people selling this stuff many times.
