Default Help w TA02 rear diff not working

Hi. I have a Tamiya TA02 Castrol Celica WRC car... got it out after a long storage, been a lot of fun, but now the rear diff isn't working at all. It's basically FWD. The main driveshaft is still there, but no power to the rear wheels. I can also rotate a rear wheel, without the other rear wheel turning. Did I strip some gears? Where do I order a replacement kit?

Thanks in advance!

I think you might of stripped the spines on the diff plate where the drive cups attach to. check that first.

Manta Ray balldiff in the rear, change it to a TA03 balldiff.
Metal of the Manta Ray is softer than in the TA03 diff. Use the diff cups from Manta Ray of they are not worn out as they are stronger than TA03....
It's a common problem with stripped splines on Manta Ray diffs.

Either that or the diff has worked itself loose. If the splines are OK, then you need to open the rear gearbox and have a look.
