30 mm tach tape. Got really lucky, as the RK and SS SD9s have the same overall gear ratio of 10.5:1
The Tachreader was secured using the bracket from the RK model. I cut it out by removing the radial spokes, leaving just the holder and the about 200 degrees of the circumferential clamp. The clamp was used to locate it the thing. The holder is fixed to the motor with Goo and Gorilla Glue Super Glue Gel. I set my tach reader tape spacing to .060"
I used all the lighting (headlights, number board, cab light) that came with the Sunset engine.
Special Thanks to Dave Minarik, who several pages earlier in this thread opened one up and showed me the PS 3 would fit. It does, but as I said above, there is no room for any wires outside the PS3 board. Incidentally, I was able to use two convienient tapped holes in the chassis to mount the PS3 board mount. That, the gear ratio, and the lighting compatibility is almost as if Scott planned it that way
Here is another photo..I blended the weathering better. And fixed the fence!
