What kind of brakes do we have? Confused...

Hello all. I'm new to the forum. My son purchased himself a 1964 Barracuda. It runs, but had to tow it home as the brakes don't work. I popped the top off the master cylinder and was greeted with chocolate milk. Delicious!

We were looking at cleaning up the system, so I thought I would rebuild the master cylinder and replace all the wheel cylinders, etc. I presumed it was all 9" drum brakes and ordered a bunch of parts so they would be here by the weekend, but lo and behold, once I got it up on jack stands and took the wheels off, the rear are 10" drums and the fronts are disc brakes. Basically nothing I bought will work, so they'll be getting returned. Nothing like losing some money in return shipping to teach me a lesson.

I based my purchases off the 1964 Valiant service technical manual, so now I'm not sure if the car's brakes were modified, if these were optional on this model or if I have the wrong manual. It's a late 64 since it has the barracuda rather than the valiant tag on the back.

Can anybody glean anything off the pics that could point me in the right direction?
