Help... 46RE Transmission - Need an odd part

I am putting together a 46re for my 99 ram 1500. The metal check ball that goes against the rooster comb in the valve body (which is under spring pressure)went mia (even though I used a zip tie-it launched). I need this before I can go any further. Does the aftermarket sell those or are they the same as a 727 trans? I would be willing to buy a whole valve body if it was cheap enough and came with this. I know rebuild kits don't have them and I have a feeling that the dealer doesn't either. I was going to check with some local trans shops too. Any help and advice is appreciated.

its the same as a 727 I believe its a 5/16 ball but I am not at work so not positive but you may find one at a hardware store

Thanks, I used to work at a Trans shop in the mid 90's before these were out but I wasn't'a builder then.

The detent ball is a 11/32".
