New master for power discs on a 70

[webfoot]

Here's the scoop. I have a 1970 that was converted to disc brakes, but was an original power drum car. The master leaks so it is going bye bye. What is the best replacement master to use or does it even matter as long as it is a 1 1/8" bore? I don't care about it appearing correct. I noticed the 81 chev 3/4T master is a bit cheaper on rockauto than one for a 71.

The only hitch I can see is that the power drum unit has both same size fittings coming out of it to the prop valve, so if there is one available like that, it would be ideal. Otherwise I can just bend my own line and use new fittings.

I have it all hooked up but haven't driven it yet.

Never thought of that, thanks. I will look that up. I found Cardone 10-1331 is that what you have?

O'Reilly's unit is sold under the "Brake Best" line but the part number is the same as the cardone unit. Wouldn't you know it is actually cheaper than rockauto, and that is before accounting for shipping.

All I can tell you is I bought it at Advanced auto parts. Only 25$ I think. This is the only way I could use the original 1970 vac booster.
