What the hell are spider gears?

My thoughts, exactly.

Spider gears are inside the differential itself.

I thought there were worm gears in there. MY BAD!

Nope, worm gears are in torque sensing differentials. There are 4 spider gears per differential, and they are different between open differentials, and limited slip ones. Two of the gears are splined to take your axles. The other two gears rotate on the cross shaft. If your rear end is stock, you need 28 spline axles. They can be had from many vehicles, such as any MN12, some Rangers, and F150s. I have some from my old diff, if you want them.

if anyone knows if the number would be stamped on them, i can go outside & read it off of one of my busted ones

The open carrier gears I have right here have no numbers stamped on them at all. Not sure what to tell ya. Just go to a stealership, and ask for stock spider gears for a 28 spline limited slip 8.8 differential. Or, just grab some from a junkyard. There's a ton of options here.
