1973 Dart Swinger Drum to disc

Has anybody used the 10.95 Stage 1 front brake kit from Doctor Diff? I want to know if I can stay with 14 inch wheels using this kit. I found out CPP kit would require going to 15 inch wheels. I' rather not do that.
those should fit under 14's, it's a stock spindle and caliper so that's a fixed position even though the disc is slightly larger than OE.

fwiw i ran stock 14" BBP rally's on the stocker discs with sliders (basically exactly the same set up)
