Is is worth the extra $ to install a new type MC instead of a factory reman unit? I just want to get it on the road safely for now; upgrades later as it will be a work in progress. Any advice/experience is much appreciated.

Better to have the original stuff. But, if you don't want to, and you'er staying with drum brakes, just go to parts store and get a rebuilt one. You already have the modern M/C.

Eventually I'll upgrade to front discs but the priority is just to get it driving safely until then. I just am trying to avoid spending money twice or three times. It's never going to be a pro-touring caliber ride, but a nice resto-mod. So, if I can get something now that would give me better performance and a little room to upgrade; well that's what I'm really asking...thanks to all...

I'd get/install one for a disc/drum app & it'll be fine for your later disc swap. live every 24 hour block of time like it's your last day on earth

And when you get it driveable,bring it up to the Hardee's on Merrill Rd, there is a cruise in there every 1st weekend of every month.

All the drum brake master cylinders have residual valves in both lines, OEM disc brake master cylinders do not have them for the disc brakes Drum brakes need around 10 lbs of residual pressure on them to kieep the linings from retracting to far away from the drums when the brakes are not appiled, disc braes do not need them or the residual pressure Mr.Cab Racing and winning with Mopars since 1964.
