Wiper arm linkage bushing FRUSTRATION!

I ordered a set of these bushing for my 87 DT from a vendor on eBay and ended up wasting my money and time. The groove in the reproduction bushings was not cut wide enough to accept the thickness of the link material. Impossible to use.

Chrysler still has these available from the dealer and they work great. The part number is 3799089 and can be found online by "goggle search" 3799089 mopar. My local dealer quoted $14 each, which from past experience with them was the usual ripoff attempt.
Online, the factory part can be found for less $5 each.
