The one im speaking about is item 5 on the diagram below:
This is a direct replacement for this bush, NO trimming or adjustments were required. The only other thing you'll need to fit this is an M10x60 bolt, nut & penny washer to go behind the bush. This will remove the original counterweight/bolt (item 9) and bolt straight up to the linkage support bar thingy (item 14).
Here's a couple of pictures of the item:
I paid just shy of £30 for these two so would £20 shipped sound ok? Im not looking to make any money on this, merely to recoup what I've spent and help someone else out.
PM me if interested.
