Bruce,
I am currently working on the install for my 901 and have a few pictures of my solution using the stock style rear mount with a little part that I crafted to make it all bolt together...
Pictures of the solution
However, I am also using the Bug@5speed cable conversion and am having a few issues with tolerance between the cable converter and the rubber mounts... Stand by as I resolve this issue because my install isn't using the stock bug pedal set... my application is 901 w/ kennedy kit connected to a suby engine.
hopefully these help shed a little light, let me know if you have questions.
