Trying to get a grasp on what a 1971 Power Brake booster looks like. Application: 1971 Plymouth 'Cuda 440+6 4 Speed Front disc brakes 1. It should be cadmium plated correct? With a bare master cylinder? 2. Where or is there a date code on it? 3. Where is the PN on it?
Photos of a correct unit?

I researched this subject for my V code ‘71 Challenger, and what I have found is that there could either be a black painted Bendix booster, same part as used in ‘70, or a cad plated style made by Midland Ross. I’m not sure if both were used all year, or if the Bendix was used earlier in the production run and then was transitioned to the Midland Ross later in the cycle. The master cylinders used starting in 71 were finished in a gray parkerized coating that resembled bare steel, though that’s based on NOS ones I’ve seen, I don’t know if 1971 production era master cylinders were still painted black like disc brake Mopar MCs were in ‘67 through ‘70.

But the corrosion coating specified for a part to be sold out of stock by a dealer can be different then what was specified for assembly line. Example the MC Lid of the Bendix sold as NOS. They were plated and not black. My understanding that this became the standard for what a car should have being restored. Yet that is not how it came off the assembly line. They were painted black. Yet you still see highly restored examples of cars with plated lids on bendix power disc cars of the 67 to 71 vintage. Plus the vendors changed. Hence all those different examples especially for the 71 up B/E bodies.

Very cool. So if someone needed one, are they available through parts sources either reproduction or rebuilt or even new?

The hemi cars used a unique and valuable Bendix booster and master cylinder. Both carryovers from 1970 and both painted black. Some 71 non hemi E bodies got the carryover from 1970 model year standard Bendix boosters, which are black. But most seem to have the Midland Ross booster which is plated. I’ve never seen a Midland Ross painted black, so the one on eBay must have had a rattle can paint job done in it at some point. 1971 is a very interesting year for E bodies because many things changed on them over the course of the production year. Some things like the changeover of the 340 engine from one plant that painted them orange, to a different plant that painted them blue, are well documented. Others like the booster are more of a mystery, 2 manufacturers were used, but was there a definite transition time on the line, or were both installed concurrently for a time?

I was looking at Rock Auto last night, & they have boosters listed. Some are send yours in & it gets rebuilt, & you get yours back. Some are just indicated to be rebuilt units, but all look to me like OE. I've never paid enough attention to them to be able to ID a Midland Ross from a Bendix. Check em out.

They come from the dealerships parts Dept long long ago. It seems like “ in a galaxy far, far away, as well. I had a buddy that worked at the local dealership that really liked me. He was the owners son and loved muscle cars. I had a 70 AAR and a Superbird at the time. I could go in and buy parts at a slight discount all the time. When Chrysler was going through the turmoil of the 80’s bankruptcy, he sold me all kinds of parts real cheap. They were cheap even for that day. I bought 4 each of the masters cly for my 70 Bird and my 70 Cuda. I also bought four 70 style sure grip units and four 71 brake boosters. The 70 booster was no longer available. One was in a kit like the one pictured. The cost for all this stuff? $25 for each. I bought heads, W2 stuff, you name it. This was before I was married. Hemi stuff was scares and I did not need any of that. Some guys had foresight and money. They bought lots of stuff.
