Scott -

At the throttle end mine does have that barrel clap - but it is not secured
with a regular screw. The set screw is a very small allen type screw. Mine
seems to be the only Non-Metric fastener I have come across. 1.27 and 1.5
MM was too small and a 2 mm was too big. Turns out it was a standard .05 (I
think I will have to verify that though because I am not remembering
exactly).

The 8mm bolt is at the front end of the bus and that attaches the cable to
the pedal mechanism.
Thanks,

Jeff
