Well first off, I dont have any.

The shifters I thought I would use were Huret Rival I believe, they came off a PH501.

I realized they wouldnt work once I took them off the PH, on this frame I noticed that the braze-ons had a built in "shifter stop?"

When mounted to the PX they just spin around. I dont know if how I'm trying to explain it makes sense or does any good for anyone.

Heres the best shot of the PH501 with shifters still on, you may be able to see what I'm saying with the braze ons


And a quick/blurry shot of the PX's braze ons.


I apologize again for my poor cycling repair dialect.
