I have ordered new differential mounts for my 300E. My main concern is replacement of the two in the top, rear of the differential.

It seems that the outer part of the bushing is a press fit into the crossmember holes. This outer part is sheet metal thickness, and it looks as if I can air chisel it out easy enough, but how tough will it be to get the new one in place? Will I be able to drive it in place using a block of wood to protect it, or is it truly a press fit?

Thanks for your help,
