Just curious & maybe missing something here so forgive me in advance...It looks to me from the pictures that the block was originally
a snow blower set up. Not an original Rupp HS40.
Again sorry if I missed something
All set on the lower throttle clamp part. Would love to see a picture of the L&R factory brake perches for a 71. I have looked at several
on line pictures. Seem to vary quite a bit. So I don't know what is absolute correct.
