The photo referenced above is the last post made by Harold yesterday showing the rod and attached pedal. I tried to copy and repost here without success.
My ‘37 does not have the original exhaust hangers, so I can’t help with a photo, sorry.
Here are photos of the Accelerator Rod and one showing the pedal. Note on the pedal photo that the hole at top nests the ball end of the accelerator rod. The bottom of the pedal nests or hooks into a bracket on the toe board.
