It's also possible to use a front caliper for a mid-1980s Corvette that has four pistons, two on each side, which does not "float". That one is mounted rigid to the spindle and it's easier to design a mounting bracket. That design has been copied by some of the racing equipment manufacturers. Rock Auto has those calipers in stock for a lot less cost than the race guys.
