I sent this info to Buddha Jones but I thought I would share it here as well. If anyone else wants to chime in, that'd be great.

- What you need is down at the bottom, endlink sets, I don't know the size though. You'll have to go to a part stores, have them get an endlink kit for the Bonnie, and measure that to get the size.
As for the rear STB, how people usually do it is by buying a length of steel tubing, flattening the ends in a vice and bolting it on to the towers. My plan was to double-bolt it on each side and see how it worked.
