Looking for a 1970 drum brake master cylinder marked AANF on the bottom. I know about the rain man brakes. But I would like to buy one from some one here. PM me here if anyone has one to sell.
Thanks

I am switching to disc brakes on the front, so my MC is avalaible.  I will check the markings on it.  What is special about AANF?

It is for the 1970 E Body only.

I'm sure I have one if no one else is able to get you one.  I just need to find time to look for it.

I have this.... but I honestly don't know if it's from an E body. Someone here should know......

I think that's for a 1970 A body . it's not a 1970 E Body.
Thanks for your time.

what is your source for this master cylinder ID info E VS. A, B, C, etc.?

got pics of the correct one?

1970 Parts Catalog shows:
  #3420961 a-body master cylinder with power & manual drum brakes
  #2808577 b, c, e-body master cylinder with power & manual drum brakes

does the a-body have a smaller bore diameter?

There's 3 different casting numbers found on 67-70 Mopar drum brake master cylinders but I've never found any differences between them other than the casting number and location of the date code. They are all 1" bore diameter.  They were used on both power and manual brake applications.  There was a dust boot to use with manual brakes that was typically included loose in the box when you bought a replacement master cylinder.
I've wondered why they used 3 casting numbers but no idea why.  Since this part was used almost across all model lines they must have made a million of them.  Maybe multiple factories and several suppliers for the castings and they used different casting numbers at different factories, or different casting numbers at different foundries?
