Hi! I am trying to build an AWD spaceframe convertible using 3S-GTE engine from a 2005 Caldina, 1997 celica manual gear box and front suspension. I also picked up 2005 Rav4 rear suspension considering Celica 1997 and 2005 Rav4 has 2.929 final gear ratio. However I would like to use a Supra rear suspension for the quality of its ride.
Could someone help sugesst ways to over come the differential ratios mismatch or anyother advise.
I do have a good steel structural engineering background
