Which power brake booster can I use

[glhx]

I’ve got a 69 dart

That I put brakes from a 74 Plymouth scamp on. Front and back disc brakes.
This has the lifted power booster

The power booster has a leak. I can hear it.
I either want to replace it or rebuild it.
Or can I use a substitute.

Rock auto doesn’t have the 74 power booster anymore. I can’t find one.
Other places do have the 76 duster booster. Don’t know if it will fit.

Doesn’t matter what goes on there as long as it fits.

Any ideas?

The picture is what I have now

Then you KNOW it will fit and work.

Last time I talked to them (about a year ago) if they didn’t have an exchange on the shelf you were looking at a 2 month wait.

They're currently at a 3-4 week turnaround on common basic ones, more time depending on the booster and any extra work (plating, etc.).
Shipping a couple oddballs to them on Monday.

I've got all winter to wait if I have to!

Any booster from a disc F-body or late A-body should work. May not be "correct", appearance-wise, but function should be fine.

If you want to swap to the later (2-bolt, plastic reservoir) master cylinder, ask for a booster (and master cylinder) for a 79 Volare.
