My recently purchased 1995 is having rear end issues. I knew it had them when i bought it, so i'm not upset, just looking at options from here forward. The car had two different rear tires on it, one a 45 series and one a 30 series. What all would be chewed up in there? Should i put in a new diff, gears, seals and the whole deal? There is a rear end out of a 99 gt for sale in my area, but from what i can find it is wider than what i have and won't bolt in? Thanks for all the help in advance.
