I purchased a base kit 5 years ago. Just recently got enough push to finish it.

I purchased a rearend from a 98+ mustang GT. I went through it a few years ago and it has 373s in it. I was planning on pairing it with a T5 WC (I already have this).

I'm curious if I'm going to need to change the gearing in it. I'm thinking the weight of the car my be to low for that combination.

The rear end is a four link setup.

Anyone have a similar setup or have an opinion? Any thoughts would be helpful.
