Correct wheel size for a vintage Peugot
A 70s Peugeot sold outside France probably used 27" wheels, not 700c wheels (though aside from the Velo Orange wheelset, you're probably going to have trouble finding 27" wheels and will have to try 700c wheels + a brake that fits it [an extra 4 mm adjustment is needed]).

The bigger issue is finding a wheel set which has hub spacing that fits this frame - likely 120mm in the back and possibly 96 mm in the front (or finding someone who is willing to cold set the frame+fork).
