Here are a few quick pics. Sorry about the size. Google seems to mess with sizes of shareable pictures simply to screw with me.
I ended up buying a trans tunnel from Billy at B&B Classics. It's and awesome starting point to build from even thought it wasn't originally intended for a Chevy II.
I've also been working on the cage and how to tie it all together with the upper cowl mounts as well as reinforce the area between the front of the door jam and cowl where I cut out a brace to make room for the cage down-bar.
This picture is before i patched a few areas - you can see them marked with silver sharpie.
