Now that we've got the '69's subframe completely tore apart, I got a chance today to look at the front brakes while tearing one side apart. Most everything, including all the brake hardware, and the driver side brake hub (busted stud hole) needs replaced.
Our budget (Ha Ha!, Dad's spending money) does not allow for a serious upgrade. But I will have to spend a certain amount even to replace these original drum brakes.
Is there another setup we could run? Like disc brakes from another type/year car that would fit a '69, and also not cost big bucks?
This will be a driver and I'd feel better with disc brakes anyways.

You can put disc brakes on the front with 90% over-the-counter parts.... totalling about $400.
You'll need caliper brackets from one of the aftermarket suppliers.... the rest comes from the auto parts store.
The drum spindles need to be modified to accept the caliper brackets and you're all set.

Then you can sell some of the drum brake odds and ends to recoup some of the money.

70-72 monte carlo, mid size gm, can be adapted, direct bolt on, except for the steering arm. Dave Pozzi has a site that has all the vehicles that can be used as doners. I just bought the whole thing, 300 clams, master cylinder booster, and everything attached to the spindle.

Thanks for the reply.
Sounds good and affordable.
What year/make/model would I use?

I used 72 chevelle. Get everything you can from a junk yard. Use all but the steering arms, yours will bolt on.
You'll want: spindles, mounting brackets, backing plates, calipers, rotors, master cylinder, booster too. Get new pads and rubber lines for sure. Calipers and rotors are up to you. I got new rotors, new bearings and races, rebuilt the calipers. Cheap and it stops great.

if the wheels will clear it, you can upgrade to C4 Corvette brakes with PBR calipers for about $500.

The E-Bay kit does not include a master cyl or booster. Bel Air Bob's does. summit does not. Toms Classics looks like it also includes the front tubes. none seem to have the front hose bracket, which is different than drums

I HIGHLY RECOMMEND FRONT DISC BRAKES. Just make sure what you buy is what you need. you may want to ask them about the brackets and lines.

I am doing a lot of reading now to find out exactly what I do need.
So far I know I don't want 17" wheels, so the C5 caliper upgrade may be out (still waiting for a return call on that).
I also know in my case buying pieces one at a time, instead of a kit may be the way I have to go budget-wise. So I may end up buying non-NOS parts to end up with '69 disc brakes.
Questions: Are the single-piston calipers worth upgrading to from drum
brakes?
Are manual front disc/rear drum brakes an improvement over all
drums?

you can use the search feature to get a lot more info than this, but...
the "splitter" under the m/c is not a proportioning valve. If you have a residual pressure valve, it would be in the main rear line under the driver side frame rail. If you just have the "splitter" under the master, you can use it regardless of your brake setup.
