Oddball car - swap to disc

Oddball car - swap to disc - ideas?

Just get the 73 through 76 A body discs brakes. Including upper control arms. Save old calipers, and master cylinder for cores. Get the proportioning valve and brake lines under the hood since the master has some unique brake lines fittings.

I haven't been able to find this setup without effectively buying a whole parts car.

The c body shoes and drums that are on the 8 3/4 will out last the pads,rotors and calipers of a disc set up by a large margin. Just mentioning this as some may not realize this. They do weigh a bit more but it is in the rear so it is of no real consequence to performance on a street car where the car hasn't been extensively lightened as a drag car.
Most (not all)rear disc kits sold are light duty parts pirated from modern cheaply built cars and tend to wear or burn up at a quicker rate than the heavy duty drums you may already have.
My intention is not to get the fur flying over these points from the rear disc guys, just you could save a good bit of cash without any lack of performance if your axle still has the brakes on it it came with.
I mostly decided to type this out due to your username being back to basics, thought it may help.

The C body axle I have is bare. It will need brakes, regardless. While it might not be necessary on a street car, I like the visual balance of discs on all 4 corners. If I am going to go downt the "fix it" road, then might as well make it look better.
The screen name is for me getting back to my Mopar roots. I still give props, you are attentive.

The '75 will have large ball joint upper control arms even though it has SBP drums. All you need is the 73+ A or FMJ spindles, you don't need UCA's. To do the OE 73+ disk conversion all you will need is the 73+ spindles, caliper brackets, calipers, and rotors.

Also, 73+ cars with drums did not have 9" drums in the front. The last year for 9" front drums was 1972. '73+ drum cars came with 10" drums and large ball joint UCA's.

I have seen FMJ in my local yards. If I grab the spindles, caliper brackets, then I should be able to buy quality rotors, bearings, and pads, hoses, then I should have front discs with 5x4.5 bolt pattern?
