89 limited slip Ford 8.8 IRS swap help

Excellent information. Thanks for being the pioneer on something like this. My questions are:

1. You fabbed a new subframe because the available T-bird frame was too wide. Correct? (sorry if I ask the obvious).

2. Do you know if the Cobra IRS subframe would work better (more narrow but expecting to lose the gas tank)

I have an F-body, slightly wider than your A-body and I admit I don't have the fab skill you have. But, I DO have patience, a good mig welder, proper tools and a car I haven't driven since 1980.

1. Not only is it too wide, it's also too long fore and aft. Mine was out of a 1994 Thunderbird Supercoupe. So many things would have had to change to make it work. In the end, I was able to not modify the car other than drilling a couple holes. Then when I sold the car, I was able to install the regular axle again.

2. Never had the Cobra rear end. It's probably narrower.

I don't have a lot of tools- I did most everything with my mig welder, a drill press and an angle grinder. It was also one of my first big fabrication projects. It was discouraging at times because the car was down for so long. But if you have the will, you can pull it off.
