sbp front disc swap for 73 dart w/ 10" drums

im used a stainlees steel brakes kit on a 10'' drum spindle on a 71 duster , came with everything , had dual patterns , 4'' bc and 4 1/2'' bc on the hub/rotors . and nice four piston calipers , in alum or iron . this kit does add width to the track so your tires will get closer to the fenders . and 14'' steel rims would not fit over the alum calipers .

Thanks for all the replies and suggestions. There is so much to consider. Amazing that one model year difference (73 vs 72 and down) clouds the water so much.
