I seem to recall the claim from somebody that built something similar that the only way to get the wheelbase under 118" with this package, is to mount the front suspension to the sides of the cockpit structure rather than having a front suspension box be a subframe in front of the firewall. I can't see for sure if that's the case here, but there's just something about feet and legs between the suspension mounts and so close to the front that I've never been particularly comfortable with when it comes to the many bad things that can happen in a high speed impact.
If you want to shorten the package and are willing to live without reverse, or use a 'bike engined car' type solution, you can use a custom adapter on the differential to install a Muncie or T10 4-speed. Saginaw would actually allow you to keep reverse too, but is not as strong.
