Larry Smith posted a pic of original clamp back in 2016. Looks like it would be easy to make, I would suggest using an aircraft eye bolt from aircraft spruce. You may have to extend the threads further on shank, just an idea.

Those hinge pin swing bolts are very close, but need to be modified to be correct.

The C clamp looks like it would be easy to fabricate.

The pedal linkage unit appears to be unused. mounts to pivot from the DS tube.
Pedal clamp is 2 pieces cast to clamp onto pedal with 1/4" bolts.
Drums are riveted together.
Obviously made for a cable that automatically equalizes.
I dont know if this is an original RM brand set or a Sunderland reproduction.

John - I have a set of both - the main bracket you are showing is an original. The Sunderland drums are cast in one piece.

When Eaton took over the production of Rocky Mountain products, they made a number of changes, some good, some not so good.

Larry,
What is the “original design” that you referred to?

Would you be able to provide more information or “photographs”.

Those following this thread would benefit from more elaboration.
