I got a mew tko600 kit from kiesler still sitting in the boxes... From my research, you don't even need the 4 speed hump to use them in a b-body... that was clearance for the shifter. Like mentioned you can clearance the tunnel some. I imagine e-bodies are the same too. My perfect rust free floor pan was already cut years ago in the tunnel, otherwise I would wait and go passion also, but this kits already here and paid for.
