The CR was set up, as stated, for a 88-93 Mustang 8.8 rear end.

I have an 1990 Mustang 8.8, 3.73 posi in my car now. It came with drum brakes. I figured I am not racing the car, and the brakes were designed for a car about 1000lbs heavier, so they should work fine for me. The lower control arms are custom from CR. The uppers are stock Mustang items.

I would consider going to an IRS, but you will need to custom build its connection mounts and shock locations. I do believe there has been some postings of folks on here doing the conversion.
