Caliper bolt anti-rattle clip
I think I had a thread on FEBO a couple months ago - trying to locate the (B/E-body) caliper pins. Couldn't find anything listed - even Rockauto. Anyway, I confirmed my suspicions that there were two different styles of pins - at least for Challengers and Barracudas. Seems that the anti-rattle clips and wire/spring clip were eliminated after the 1972 model year, and, the caliper pins became shorter. My '71 Challenger had these parts while my '73 and '74 cars did not. My current '73 has original pins and they are shorter so cannot accept either the clips or the wire spring. So, about two months ago when detailing the '73 front brakes, I decided to replace the pins, as they showed wear at the point where they pass thru the pad plates. I could not find them readily - especially the later (shorter) style. The only listing on Rockauto I could find was when I typed in a number from about 20 years ago. It is No. H5017-2 by Cooper/Wagner. I purchased four and confirmed the difference to the later version when side by side. They fit the same as OEM but just stick out a little more inside and outside. (see pics). Bottom pic has original (shorter) pins. From what I could determine, there was no need for the clips or the spring so Mopar just eliminated them - and shortened the caliper pins - after the '72 model year. The pin bushings and wire clip are readily available - but not the shorter pins. Point of all this is you should not need the extra parts for your '72 since the calipers are same as later years. Rumor has it also that the metal clips (next to the hex end of the pin) were not there to reduce or eliminate any 'rattle' - but only to keep the larger bushing from working its way out of the bore. IF this bush has a 'flange' on both ends, it will stay in place in the caliper and therefore no need for the metal clips. And, when I installed the new/longer pins, I had three choices: install the long wire 'clip' that hooks onto the pointy ends of the pins - or- cut off the extra length that sticks out of the small bushes - or - install these longer pins 'as-is' - and this is what I did.
