Looking for info on Correct Booster and Master Cylinder for Power Drum brakes

Can some one provide part number and pictures for the correct Booster and Master cylinder for a 440 Auto Daytona with Power Drum brake option.  B51 only.  I have seen plenty of different variations on supposedly correct cars.  Also did the 440 cars come with Saginaw power steering pump and cooler if coded for Power Steering?  Thank you.

So it is the Midland with the screw on Clamp type MC.  I have seen several with a baby looking Bendix type.  Not Bendix but a small look alike.  They also use a clamp style MC similar to a disc brake car, but smaller and equal reservoirs.  How about the power steering?  Part numbers appreciated also.

The picture below is from a B51 (power drum) Daytona, 11,000 miles at the time.

I think the part number for the Midland-Ross booster assembly itself is 2883042, with a booster & master cylinder (combined) assembly p/n of 2944277.  That particular Engineering Illustration page is very confusing to be honest.

The assembly-line master cylinder p/n  by itself is listed as 2944274, which is a different part number than the parts books show.



IIRC, the Saginaw PS pump received the cooler if it was installed on an axle package car (A32, A33, A34, or A36, which is nearly all Daytonas).  That would hold true for 440 cars... I've yet to see an original 1969 Hemi/Federal PS pump with a cooler, regardless of axle package.

Thank you, your always very helpful.  What are these engineering illustrations you mention when providing help?

If you are looking to buy, call these guys first.    They know Mopar and will set you up with the right stuff.    I have used them several times.

I've never owned anything but a MoPar. Can you say that?

I agree with Geno.
Here is a chart showing part numbers....and maybe more importantly - casting numbers. And another pic of the booster/master.

Thank you, appreciate the confirmation.  I have seen several with what looks like a baby Bendix type.  Not sure who produced it, but it has found it's way on to several daytonas.  Is the Midland that hard to come by?  My cars are powered Disc so I have the Bendix and an original spare.
