I watched the Spirit video where he added 4" to the cowl. Doesn't look that bad. I thought about doing it a little differently but, the use of honeycomb (plasticore?) seems fairly straight forward.
This is a old body, I think it was made sometime in the 60's. I picked it up for my project. Ignore the frame it's sitting on.

The firewall is smooth though, it doesn't have the lip that Sprint used when he cut the firewall to move it forward.
What I was thinking of doing was making a template out of some 3/4 plywood to match the firewall. This would become the new firewall.
Then cut the firewall out about 1" undersize. Leaving a 1" flange around the whole thing.
Glue some wood to the flange, 3/4" wide, basically creating a lip for the honeycomb of 1/4"
Glue some wood to the new firewall, same deal.
Then just run the honeycomb lip to lip, resin and glass over.
However, before I go crazy with the body saw I was curious if anyone had any feedback or suggestions.
I've also thought of (and this might be dumb). Instead of lengthening the cowl, cutting the body in half and lengthening the actual body. I thought about doing this by cutting the doors (and body) in half, and making the actual doors longer. This of course would require me to have to cut into the lovely wood work on the top of the tub.
Feedback?
