Let me take this to another level: Why put so much money into a powder coat for a common Peugeot with the incorrect fork?

You can fairly easily find a great condition original bike that you could hack up with relative impunity. Granted you will get less CV flack with an abused frame, but a quality powder coat will eat up a lot of your build budget... and you will loose the really beautiful vintage Peugeot character. I say rattle can it if you are going ahead with this frame.

I have a great one you can come and get for a good price. Long drive though.
