front spring eye bushings?

Call Mancini and talk to 'em about exchanging what you got for what you need. I've always had good luck admitting that the fault was mine (even when it wasn't) and asking for help getting the right stuff. I notice the PST page says you must specify the diameter of the bushing that you need. Seems like that's the mistake that was made, either on your end or theirs. Shouldn't be a major glitch to iron out.
