89 limited slip Ford 8.8 IRS swap help

Geometrically too long fore and aft (interferes with how it would operate) or is it just because of the gas tank? Because I'm switching to a fuel cell as I'm lowering the car and would prefer a speedbump not knock a hole in my tank.

One of my goals was to keep the stock tank and keep the car intact. So yeah, the Thunderbird subframe would have eradicated that. The T-bird lower control arms were massive and cast iron if I remember correctly.

Have you got your set up yet? Just throw it under there and start measuring.

On the weight, the car gained about 100 lbs but it also had the tiny 7.25 axle before. I think if I would have refined the design, I could have made it lighter too.
