Thanks guys! The feedback and compliments are much appreciated.
I've slowly been acquiring parts. I bought a true-trac today so I can get my other 3rd member back together with 3.89 gears. I've also started to look at how I'm going to seal the tunnel back up. I'm hoping to make a section removable but it depends on how it works out where the tunnel meets the firewall. Tying this together looks challenging.
