Default Vintage KYOSHO OPTIMA MID parts

Hi I am looking for the rear differential gear for a kyosho optima mid series.
I think the part number is SG-25 on the exploded view diagram.
If anyone has one or if they no were I can find one that would be great.

Sorry to say but they but Mid gears are so expensive.

Found the gear set for you as I had to replace all the gears for my Mid Custom not so long ago.

So I bought a rough Optima Mid SE to get the ball diffs out of it. Then bought the Ball dif gear set

Then the Idler gear and top lay shaft from the Fire Boys E bay shop . The first link.

This would be the best way to do it. Optima Mid rear ball diffs are very rare now too for this reason I say.
