If it can go wrong it will. I set about rebuilding my brake calipers. Ordered the rebuild kits from Centerline. While waiting I cleaned the calipers and removed the old seals. No I did not split the calipers (I know some of you thought that was were I was going with this) What I did was even stupider. Assuming the rebuild kits would contain new retainer clips for the dust covers I tossed the old ones. Trash left on Friday. Rebuild lits arrived on Saturday, alas the Centerline kits do not contain the retainer clips. I ordered new kits from Performatek that do containthe clips (BTW they are more than twice the cost). Andy is a great guy but it took him 3 weeks to get them to me and then he was backordered for the front kits. Does anyone have 1 retainer clip for the front of a 71 spider (I think 71-74 will work) that they are willing to part with? I have 3 front retainer clips. I am 1 clip short of a full load! (or 1 brick shy of a full load). Please send me a personal email and I will provide an address. I will gladly pay anything reasonable and reinburse the shipping cost.
