We, Rudy and I had to abandoned the ford 9" because of the cost , u had to buy a special housing for around 2000, the gears around 400, the axles for around 500 each and the R & D would cost us over 10000.
So I am doing a 3.46 Mercedes diff set up for the Crossfire for 3780, supply your diff and tcu get 500 core back,,, now for the 6 speed it is 5 or 6 hundred less because u don'r need a tcu ,,but have to look at my price sheet to be sure of the prices as i am not at home this week,, Oh, this is with a new wave trac but if u if you have one it is 1250 less again. lf u are interested in a 3.27,,3.46,, or for those people that wanr it,,with 6 speed we can do a 2.89 jim
