AMC 20 traclock ratio switch 331 to 373

[Sparky]

My rear end has gone to Davy's locker... I will be changeing the ratio asap but what locker/limited slip???? for front/rear...

i tried to find 3:73s for my fsj but was unable to do so because my parts guy couldnot find them for a 20 . i think 4:10 s are the next best upgrade and they are avail for 20 and d 44 if i am wrong we will find out . as for lockers i don't use them i like posi front and back but if i was going to run a locker it would be a detroit locker.

4 wheel parts has the 373's , would I have to change the diff casing to go to 411's??? This is a new project so any advice will be welcome...How are the edelbrock goodies working out???

my edelbrock intake is great. i have had to mess with the carb a fair bit but it is allmost there . i know for sure that with 4.10s you would have to change the carrier . as for the four ten four eleven issue i know for sure that you can only get 4 10s four the 20 b but it will be a seatof the pants difference. in canada a stock carrier set it about 240 dollers canadin and i love the stock posi units you could get two for the price of a detroit locker maybe less
