Sounds like stock TR8 in that case. Now that I think about it, I do recognize that part number. Pretty sure last time I checked the ones on the shelf there were two numbers 3244 and 3245. Back in the day it was common to use Ford Capri calipers instead of the TR8 ones. They were almost identical except the Capri used the same pad as the 240z. 240z pads were 1/3 the cost of TR8 pads, and were available in more racing compounds. The fact that you could walk into just about any parts store and buy a set rebuilt for under $100 with no core charge was nice too. Sadly these things are mostly gone now, so finding them can be as difficult as finding TR8 calipers. But on the good side Willwood makes a great caliper and you can put together a big brake kit for the front using Willwood hats, rotors, and calipers for around $600.
