1970 Challenger RT/SE Looking for a Master Cylinder

Hi Everybody,

Looking for a reliable source, I need to replace my master cylinder.

Thanks

If it's your original it should probably be restored/reconditioned & reused....Joe

If your car is a disc brake car and you have a OEM correct 2229171 master cylinder on it, they are very valuable and you can have it rebuilt.
If not the original, the best one to use is Raybestos or NAPA United MC36307.  Those are technically the 1971 up style disc brake MC, but look OK and work well.
The drum brake MCs are available from a number of sources like Rock Auto.  If you have an original it is worth something as a core.
