FLM Savage Combo Bulks
 

I purchased a set of the FLM4000 Savage Combo Bulks, and after rebuilding my diff's I went to stick them in the bulks, only to find that the drive cups wont fit through the holes in the bulks. After staring at, from many different angles, I still dont see how these are supposed to work. My one biggest complaint against FLM is the distinct lack of any and all instructions and information to go along with their products.

If anyone has any idea what I need to do, please let me know. I'm almost guessing that these are meant to use different diff's than I have (Flux).

Edit: The diameter of the outdrives are .640", the holes in the bulks are .628 for the bearing recess, and .595 for the "thru hole". Does anyone have access to some Savage X or XL output cups to see if they are smaller in diameter than mine?

Edit part 2: I think I should have ordered the FLM40010 bulks - they are for the XL, which I believe came with larger cups.
