I believe the ford ones used a different thread for the line connection.

Depending on the year of the Ford caliper 3/8 or 7/16.
You don't use Ford parts like that on a Mopar caliper, and then you don't use Mopar parts on a Ford caliper.
Basically the same caliper, but with differences between Ford, & Mopar.
