I will have 15's (bundts) on my CD once I mount tires.

If you go with the PRE 1986 SD (vented) front rotor, you'll need a different caliper, the thickness is different.

First pic is a 123 front rotor, the second is a 126 front rotor. The calipers have different part numbers.

The diameter may be the same and it doesn't matter about 14 or 15 inch wheels.

OK thanks. Was there ever a Bendix caliper in the W126? I like the Bendix design on the w123 better than the ATE.
