Reference the floor, tried Brookville Roadster. Loved the look but did not allow enough set back. This is Direct Sheet Metal (Dave). He is from Bitchin. Very helpful. I highly recommend. I am trying to make this firewall floor air tight. Not visible from the inside and only after I took the old engine out, I did not realize there was a 3/8" gap between the firewall and floor!! No wonder I had to drive with the windows up.
