I have a 1995 Subaru Liberty LX and unfortunately it's only FWD

I'm looking into making it AWD but i just can't find anything!!
I know a bloke whos selling the rear diff and suspension from a 1989 Subaru Liberty, but will this fit my car??
thanks

Normally Gen 1 manuals are 3.9:1 final drive, Gen 2 is 3.7:1 final.jimmeh14 wrote:how would i find out about ratios? i dont know much about that.
