I have a 1978 Dodge D300 Clubcab with a 440. I need to replace my power brake booster and master cylinder. I can find master cylinders all day long, but cannot find a rebuilt booster. Rockauto has exactly what I need under Part # 503122, but it is an obsolete part #. Rockauto lists the booster only under Part # as 5473122. It too seems to be obsolete.

Any suggestions on where I can get a direct-fit replacement booster? I see NOS ones on eBay, but they're $400. That's way over my budget.

Any assistance would be very appreciated!!

Nice truck... Welcome to the site...

Thanks for the link. I’ve tried NAPA, Auto Zone, Advance Auto, O’Riley, and the local parts places. They all list it, but when I try to order it they say it is out of stock and unavailable.
I can’t be the first guy to need a replacement in the recent past, so I’m hoping that someone can offer a suggestion or solution.

Have your local parts house ship it out for overhauling in that case..... A1 Cardone comes to mind.

I guess that might have to be my only option. I just can't believe that I'm the only one to have faced this issue.
