I deceided to try the technique of modifying a stock Gitane bridge by hollowing out the underside with a Dremel tool,as suggested in a previous posting. It worked beautifully, better than I would have thought. I left a 2 mm wall and basically doubled the amount of the hollowed out area, extending it a bit more into the feet and shaving the ends in the way the original Selmer is done. I used a cone shaped metal bit and carefully increased the original routed out area.
The sound is louder, and dryer much like the Shopis and Park, and Lehmann guitars that I've played.
The result is great, and the fit and intonation are perfect. A few minutes work was well worth the efforts. I couldn't be more pleased.

I've found the Dupont bridges to be excellent for tone, volume and intonation on the Gitane. As Jacques says, they are "a dead copy of the original Selmer bridges".
