On the way to camping my truck got the shakes.

[phlegm]

As some of you know from the General board I took my 71 camping for the first time this weekend. I got about 2 hrs away and all the sudden I felt vibration and heard very rough engine noise, I thought maybe my exhaust gave up the ghost. When we pulled in I popped the hood and there was my AC compressor, pulley still spinning with a piece behind that that was apparently attached to the pulley at some point, spinning out of whack. The Belt was pulling the engine out of balance, thus my noise and vibration. It was easy enough to get back on the road, I just cut the belt and went on.

Anyone ever have to replace this piece, I noticed you can buy it separate from LMC, for 49.95 and did not know if this was a good price or if I needed to get it from somewhere else?
