Dave P. makes the adapter - I designed the hub and get a local CNC shop to cut it. The plate is supplied without any holes except roughed in dowel holes. Its water jet cut.
I'd have to check with Dave on the plate cost - don't remember what I paid.
3:54 which is the lowest numerical gear I could get for the dana 60.
I noticed quite a difference in mileage between the 9" and the dana. Close to 2 MPG.
