I will try the heat gun and weight this weekend. After bending the carpet around I don't think it will be that hard to fix.
I made some progress on the conversion. I've installed a Ramsey 9.5 e winch and a Hustler whip antenna and ball mount with the help of my Dad. It was so much more tedious lining everything up than I thought it would be.
When mounting the whip antenna I masked off ball mount point to help prevent rust and hopefully create a better seal with the gasket.
I think my next step will be finding the correct rims and semi-correct rear fog lights.
