So i got this new MAF off of a pre 90 firebird fresh from the junkyard (it looks good), but when i went to go put it on my 87 350, i get down there pull if off, cut the clamp things off and the one i got is a wider 3 prong connector as compared to my smaller 5 prong connector.... what does this mean? and can i go back to the yard tomorrow, cut off the clip that was on it and swap it for mine? please let me know i want to get my buck taken care of tomorrow
