Frankly, OLDER french bikes (pre 1980) and early 80's Japanese upper end Univegas, Myatas, and Fujis (with decent Tange tupes) are by far the best conversions. Your likely going to have to hack on that 531Pro to get it right, and with th shrt dropouts and light tubes, it won't last like the others I've listed.
Just my opinion. I firmly believe it's your bike and you can do what you want, but it just doesn;t make sense to me.
Sheldon Brown has done the same with a number of 531 bikes. I did some googling and here is what I found about the model I have:
From the research I've been able to do, I believe this 1987 bike is the very last model PX-10 that Peugeot produced. Specifically, this was the PX-10 SH ("SH" for Shimano?) "Puymorens" model. This model was produced for two years, in 1986 and 1987. The earlier model had a chromed fork and the Shimano 600 EX group. The 1987 model had the painted fork and the new Shimano 600 Ultegra group
So I have acquired one of the last PX-10 bikes Peugeot built. Mine has the chromed 531 fork and chromed stays in the back.
