You can swap around any f series gears.

I have 4.1s from a lexus for sale but thats well shorter than your needs. If you decide to rev the engine 3000rpm harder let me know, haha.

mx73's are 4.11 i think, auto ra65 is 3.8 maybe??? thats what i have in my rt142 (irs). std rt142 manual is 3.5or6 ish cant rember and for whatever reason it dosent have the axel/trans code stamped on my data plate for whatever reason

yeah ra65 auto is 3.7 from my searching, As is RT142 IRS Auto. Just turboed the thing and with the 4.1 it eats gears wayyy to quick! Dont wanna rev it much past 5500 it will just kill it
