question abotu rear
 

I was wondering if the GT rear just bolts right in or would a person need a new axle and all that?

If it is from a 99-up car it is a direct swap.

You can use the 94-98 rear, but the brake line routing is different on the 94-95 cars and the rear end is narrower by 1.25".

they'll all bolt in for the most part. little things change but nothing worth stopping for... at worst it's a parts store run away.

Get the drive shaft too.
