Hmm - $45. As I posted about the LCA - - similarly a good idea to remove the upper to replace the two (on each side) inner bushes. Lots of good, used UCA's out there - or new. Why replace inner bushes and upper joint (on smaller unit) and then have to 'fork out' another $50. (plus shipping?) for the adapter when you can start out again with (correct) B or E-body large UCA.
