Jim, you are going to have to pull one wheel off at least.  You will
either see ATE or a large G in the center of the caliper body.  Just
bundle up.  Just FYI but we sell brand new calipers for $79 each.  They
require your old ones as a core (not sure why) but the ones are get are
brand new not rebuilt.  You could just order a pair and then you
wouldn't have to worry about ATE vs Girling because as long as you
replace them in pairs either will work.  Just a thought.
