hi i am the owner of a mitsubishi evolution 7 and i am from trinidad... my problem is i got a RS rear differential setup installed in the back and there is the acd transfer case upfront... the rear diff is making alot of noises so i believe that its on its way out.. its a bit hard to get an rs rear diff in my country because the evos that come here are all jdm so it has ayc. can you guys tell me if the galant rear diff can work in place of the usdm evo rs rear that i have on now or what can i use with advantages and disadvantages. thanks!
