RPM 10T Rear Hub Bearing Size?

I got a pair of RPM rear hubs on a RC10DS from treehugger. He had 3/16 x 3/8 bearings in it, but if I kept these bearings in and drove the car, the complete assembly would fall out! As the hubs have no inner bearing retainers! In other words, the hubs have a 3/8 hole from right to left! I assume, these hubs should use a flanged 3/16 x 3/8 bearing right?

I looked on RPM's site and only found the bearings for the GT type hubs. These are not the same. I don't have pictures of my RPM hubs but they look like the 10T/T2/B2 type. I would like to use these hubs on my RPM Tiger RC10T. Do I use flanged 3/16 x 3/8 bearings? I'm thinking the axle will be too short to make up for the extra width of the flange?

rpm had hubs for flanged and plain bearings. if there's no retainer for the bearings, i'd say it should use flanged bearings.

Thanks scr8p, I ordered some from Boca Bearing. I hope they are right!
