    Can anyone share photos of their floor pan modifications for a 3rd Gen B body with a tr6060. Im currently swapping my 71 with a 6.1 crate and 6060...just finished up a new American Autowire harness swap, now comes the fun part, stuffing a new drivetrain in!

    Not sure if this helps but I put a 4L80E, GM 6 speed behind my 383 and di massive mods to tunnel nd frame supports for the tranny. This is a picture of tunnel, going from OE 727 to the huge GM. Good luck with your mods! Mocajava

    Its not just the pan, its the entire torsion bar crossmember too. You really need the trans up in the tunnel to get the driveline angles correct. See attached for what I did. The TR6060 has very limited crossmember mounting options available and you will likely need to make your own mounts and reinforcements. The stock Challenger mount sits wayyyy too low as I found out. I used a modified Holley adaptor meant for a truck hemi swap and made my own crossmember and new support.

    If I had to do it all over again I would have used the US Car Tool perimeter frame kit with their TR6060 mount:

    Yes it is expensive, but you would save a ton of time and headaches. I installed their full chassis stiffening kit and it was all top notch stuff. Everything of theirs that I touched clearly had lots time and engineering put into it.
