Some semi-complete pictures of the chassis, note that extra gussetting was added in some places. Total chassis weight without front and rear crush structures was 470 lbs, pretty good considering a Vette frame is 420 with no crossmembers or roll cage.
The lessons learned are
1) the aforementioned firewall should be welded in stainless instead of the honeycomb.
2) I could have used more 2*2 on the lower rail instead of 2*3 for everything (about 8 lbs of weight savings). I used what I had at the time.
3) I would have liked to carry that small tube above the main rails that attaches to the cage side bar all the way from the rear cage post to the front firewall post.
4) there is another 10 lbs I could have whittled out of it in a few places.
Next week I will get into the suspension buildup or the body mounting.
