Brake Rotor for the M500
Centric Parts 120.67010
The dimensions are the same as the KIC 666-13380 that has been listed here previously and it is available through Amazon.
I saved a few bucks by ordering from Amazon themselves as I was just stocking spares. It took them a month to get the first one and the second one is due here Monday. Others sellers also have them for about 20 bucks more but they are in stock.

I know this thread is old, but I never saw a post that Definitively says that the Centric 130.83006 master cylinder will work on Late M375 chassis. MY 1972 Dodge Travco.
The casting on the new master is 30042-C. The only difference I see is that the Front port will need a 1/2" to 7/16" adapter. (I saw a thread where someone paid $400+ dollars from Alretta that had this exact casting with the adapter) I paid $180. I am installing it this weekend and i'll report back if it works.

The Brakes seem to be working fine after replacing the new master cylinder rod with the old one. So the Centric part # is correct for the M375 late chassis.
