These I got from the good Mr. Shea fresh from a rebuild. They were machined to custom fit application before I purchased them so the ears are thinner by the width of one washer, meaning you need to use a washer on the inside of the caliper ear like some Ferrari calipers. I test fit them and they are a nice fit with a standard fender washer. I went with a custom setup up front so I was saving these since they are so nice. My race car is done so these need to find a home putting some serious stopping power on some other car. I paid $200 with cores.... and flat rate box. which was a screaming deal so I'll pass on an even better deal to the next guy.
$200 plus flat rate box fee and NO CORE CHARGE.
If ya have cores, then just give a good turn and send them to PMB.
