You can use the dark red part as bleach if you add lots of Bromide, e.g. 50 g/l Ammonium Bromide. The second part, a yellowish liquid can be used alone to make fixer.
So it's not as simple as one part being a standalone bleach, and the other being standalone fixer. B is a standalone fixer, but A depends on B to work?
Since I haven't been able to find the Fuji kit Stateside, what's the best way (short of mixing bulk chemistry) to do a non-blix C-41 process in small quantity?

Part A converts Silver to Silver ions, and Part B forms a soluble complex with Silver Ions. If you leave out Part B, you need an anion to make the Silver ions happy, preferably one the Silver ions really like, e.g. Bromide.
I have seen a (there was a url link here which no longer exists) where someone just tried to mix Part A and Part B into separate bathes and he got brown stain on his slides - an indication that Silver was left behind.
