70 dodge challenger booster and master

[70rtse]

Hi guys looking at getting my brake booster and master cylinder overhauled

Not sure if this booster is correct for 70 dodge challenger
The master looks original.

 Your booster appears to be the Midland-Ross booster used 72-74 just painted black.
   First clue is the band clamp that are not used on the Bendix booster.
     Good Cores for both are hard to find from what I'm seeing

Found a decent comparison thread here, about the 10th post has correct '70 booster  http://files.mpoli.fi/The.Dodge.Challenger.Message.Board/challenger.mpoli.fi/board/topic-5442.html

Those parts you have will work, but as mentioned "not correct" for 1970.

Can you buy reproduction brake booster and master that are correct

[JH27N0B]

By correct do you mean OE appearing reproduction parts?  If so, no.
If you mean correct in that they will work, sure.  The original one year only 1" bore master for 70 E bodies is very hard to find and expensive if you do find one, but the one you show, Raybestos MC36283 works and has a 1-1/8 bore, the MC36307 works and looks a bit closer to original and has a 1-1/32" bore.  Paint it black before installing for a closer to original appearance.

Guys, for the Master Cover and Wire Clip, both are painted the same black as the master body and booster correct ? As shown in your reference picture.  Sometimes I see Master Covers as Yellow Zinc/Cad plated and not painted black

In 1970 it's fairly safe to say that ALL E Body power brake booster/master cylinder assemblies were painted complete black. They were delivered to the assembly plants by Bendex as an assembly, so everything was painted as one....cap and bail wire....everything.

Disc brake masters were painted completely black.  I've never seen any evidence of drum brake master cylinders being painted black, regardless of whether they were on a manual or power brake equipped car.

Are the brake boosters the same for 70 disk brake and drum brake front end

Obviously the master cylinder are diffrent?

Are the brake boosters the same for 70 disk brake and drum brake front end
