Thanks for the guidance guys.
Unfortunately I do not know exactly what buggies these parts were made for. I just kinda followed the cheap reverse thread and bought similar parts since the links were old.
The gearbox just says GY6.

The output shaft. 197mm long

I wonder if this is the one I need? It's listed as 204mm long

And a 39T sprocket from BigE on the other site.
If BD had any in stock I prob would have bought that kit and been done with it, but they have been out of stock on stuff for a REALLY long time..... (although I saw a couple listed yesterday when I was doing some research. UGH!!!!)
Unfortuantely no spacers came with anything. I had to re-use my stock spacer and add quite a few myself as you can see.
Hey X-bird, do you remember off hand what length output shaft you needed?
As for the flakes, there's lots of grease on the inside. The metal flakes are from the 2 case halves touching when I put it into reverse and start spinning the output side.
