Are these my original 1970 calipers and p-valves?

[7E-Bodies]

I really need some lessons as I'm weak on brake part ID. Especially on proportioning valves (if that's what they're called). I also need some feedback on a place called Brake Warehouse as I'm about to send a very rare 2229171 master cylinder to them as well. Several questions. Are the calipers correct for an 11/4/69 SPD Challenger RT? Should I send all parts to this place at once? Do all of these parts look original/correct? School me, brake people.

They do not look like 1970 calipers to me.  I would say no, not correct for 1970. 

The 1970 calipers had 2 dimples.

Got another parts bin with brake stuff the seller gave me. Let me check that and I'll post anything I find.

here is a correct for '70 E & B-body disc brake caliper KH80012 "BIG MOUTH" 

the "big mouth" on the back-side is an easy ID of this one year only part (very early '71 also)

[6bblgt]

& just about everything has a date code or two

caliper 1152 = MON. 4/24/72
bracket 266 9 = TUE. 9/23/69
caliper 277 = 10/4/??
bracket 280 = 10/7/??
caliper 148 = THUR. 5/28/70
caliper 182 0 3 = WED. 7/1/70 3rd shift/line

@6bblgt and @Cuda Cody is this better?

Correct calipers for 1970 will have number KH80012. Hard to find. I just sold one

As for the other part of your question about Brake and Equipment Warehouse.  I had very good experiences with them.  In fact, I sent them my 171 m/c for a rebuild.  They did such a nice job that I later sent a set of 70 calipers to them as well.  Great service, knowledgeable and friendly.

[6bblgt]

@7E-Bodies those all appear to be newer than '70 calipers 

[7E-Bodies]

@Floyd very helpful. Thank you! At least I can reach out to them tomorrow for my 2229171 MC. Heartbreaking about the calipers not being original.

@6bblgt again I tip the hat to you. Very much appreciated.

I bet I have some good 1970 cores if you need them?

[7E-Bodies]

Well, my parts all just came back from Brake Warehouse in Minneapolis. Can anyone chime in with the proper paint tone for the 2229171 MC? They offered to rattle can it, but I opted to do it myself with perhaps some better stuff. Also do the calipers get paint? (70 Challenger RT, 11/4/69 SPD) Also thoughts on the MC cap originality...

Master cylinder and lid  should be a 80 percent gloss black.  Calipers were left natural.  Not sure of the best option if you're going to paint the calipers.

Did the Brake & Equipment guys rebuild your p-valve?  Looks nice.

[7E-Bodies]

Thank you and yes they did.
