I've been having a problem finding the right master for my car. I received the 3rd one today and again, this one is for a disk car(large rear reservoir). This last one came directly from the factory and is p/n 10-1493m. Everywhere I find it on-line the picture is correct and looks like original with same size res, but that's not what is in the box. Summit's been great but they're saying maybe the wrong part came in the box(again?) and now the factory is out of stock. What is so difficult about this master? Nobody has them and oreily can't even get them. Any sources? Of course I broke an ear of the original. The casting numbers are 3461189 on my original one, and 3461137 on the new one.

Bomber,
The 71 Challenger 4 whl drum master is elusive to find thru various manufacturers, I've been in the same jamb trying to find this master...if you have a parts store that carries the Fenco line, which I find very good at supplying vintage/correct masters, Autozone, if avaliable in your area, carries the Fenco line...Fenco PN# M1323 or NAPA's TruStop line of new masters PN#10-1323, I'd recommend the Fenco line
The top lid and bale clip are slightly different than the original, if you still have your original cap and bale clip, they will swap over to the new master

Re: the fenco. The first master I started with was from my local Autozone. It had a bolt in the middle to hold the cap on, but the biggest issue I had(and it looks to be the same in the above pic) is that there was a tab on the mating surface to hold the piston in the master. To use that master, I'd need to trim the firewall for clearance. That didn't seem to me something I should need to do for a "replacement" part. Maybe I was wrong?
Aaron; the master you received with the bolt on cover (Fenco) using the 1323 number....all it takes is for a counter person to either look up the wrong part, or enter it in the system wrong, or pull what appears to be the "correct" part based on many variables...the bolt on cover design you received was Fenco PN#NM1323 had they pulled/ordered Fenco PN#M1323 you would have recieved the master I posted a pic of earlier...
Regarding the tab in the back of the master, IIRC the heavy duty reinforcement plate that fits between the master and the firewall, will have a slightly diamond shaped clearanced hole where the master's pedal rod travels thru, thus the tab and flush screw clear the plate and mount the master flush flush

Here's the Fenco Master NM1323 which is incorrect for your application, one letter added makes for different results

I'd consider the one on Ebay, but it is for POWER drum brakes and mine are MANUAL. I think that's the root of the problem. My re-enforcing plate has only a round cutout(hole).
