Buying the Hemi and transmission is a deal. The big drawback was cutting up my trans tunnel. It would be too much modifying the car to fit it. I went with the 5spd TKX.
Straight up fact right there, I had to end up fabricating my own tunnel. By then I was so frustrated I made it a bit larger than needed so that I could get to everything underneath. In retrospect I should have fabricated it a bit smaller!
