I'm kind of in the same boat as Ritchie.

I was originally looking at one of the Skyhawk II kits, since I'd prefer a 4-stroke, and I'd also prefer an in-frame install.
But none of the rear sprocket's look like they'll fit my bike with the drum brake on the rear.

There's just so much to sift through on Fleabay, and all the kits appear similar, but after reading the forums I see that there are subtle differences in the kits, and especially the quality of the service you get from the seller.

Anyone know if what I'm trying to do is even possible?
4-stroke, in-frame install, and compatible with a rear Drum Brake setup?
I'm not totally lost, but a point in the right direction would save me some headache and worry.
