Re: 2006 Kit of Part Transmission

Here's the link to IFI's CAD model of the 2005/06 Season Kit transmissions:

If you have access to CNC fabrication services, it would be easier to reproduce the AndyMark single-speed transmission as opposed to the IFI ones.

The AndyMark transmissions are essentially exactly the same as the IFI trannies*. The IFI transmissions however used a custom cast aluminum plate (which would be much harder to reproduce), whereas the AndyMark transmissions have two machined 3/16" aluminum plates, with a piece of square box aluminum around the outside. (You could probably eliminate this square box and just use aluminum hex/round stock as spacers if needed instead.)

* The IFI transmission had a 12.755:1 ratio, where as the AndyMark has a 12.75:1 ratio.
