1968 Formula S...modify it beyond return?

I'd hate to see a really nice Formula S mini-tubbed but everything else is fair game to me. You have nice wide rear wheel wells as is. But like others have said, it is your car. I have spent a lot of money replacing the oil pan, air cleaner, console, original trans, and other parts I threw in the landfill, for my 68 383 Formula S. Not to mention the B & M Starshifter, Centerline wheels, and Fiberglass Hemi front clip that I did not need to buy. The 68 Formula S is one of the coolest cars ever made by anyone.
