Flexicolor Part A Developer Formula?

I bought 2 old flexicolor developer boxes recently, each containing part A, B, and C to make 1 gallon. The problem is, the part A's leaked in shipping; one is almost empty.

Does anyone have the recipe for part A? I'm willing to bet it's C41 minus the hydroxylamine sulfate and minus the CD4. I figured that if so, I could use my homebrew recipe to approximate the part A.

I assume part B is just hydroxylamine sulfate, and part C is just CD4. Can anyone shed light on this?
