I highly recommend the GREASABLE Prothane 1" Style "A" bracket (19-1158) over the NON GREASABLE 26mm Style "B" bracket (19-1142). I've had both and the Style A bracket has much shorter mounting "legs". The Style B bracket sticks out beyond the end of the frame.
I have a Style B bracket on Trooper #1 and Style A bracket on Trooper #2. I can take pictures if you like.

The numbers you posted are NON GREASABLE. I recommend the following GREASABLE bushings:
