Hello all I have a 4cyl mag up for bids on E-bay item# 3839929386 The question of the day is, What's it off of??? I'm guessing an f-12 or f-14 but may be way off base. If any of you have the time and a little knowledge of mags I'd sure appreciate a little input on it. Bob Some people call me Sweet Ole' Bob, others just use the initials!
