[Closed] Prophet advice please

Morning chaps

I'm in need some advice about Prophet front mechs.

I recently bought an old prophet frame off eBay. It was pretty neglected state including a seized shock but bringing it back to life was surprisingly pleasurable.

However in my excitement I hadn't noticed that there was no BB extension plate for the e-type mech.

I tried to fit an old bottom pull mech of a Jekyll but it fouls the middle ring no matter how high up on the seat tube I fit it.

Is it possible to fit a seat clamp front mech or do I have to hunt down a BB plate?

Any real world advice gratefully received.
