For future reference, I ordered Moog Problem Solver replacement upper control arm bushings #K6176 for my 84 Regal. They no longer are made with the "teeth" or serrations on them. No work is needed to modify them. I spoke to Moog and was told they stopped making them with the serrations in 2014. If you get a set of these with the serrations (and you probably will), they are old stock that have been sitting on a shelf somewhere. These bushings fit all of the GM G bodys and S-10's. Don't know if Moog bushings for other car models are done like this or not. And Mark was right. They do not need honed. They slide on easily as is. Great "dime rocket" parts.
