Eric,
Could you give me some pointers on measuring, reenforcing, and moving the firewall back. I am using a YS 120 with "A" type Hyde mount and I am way too forward of the cowl opening. Also, exactly how did you mount the tank under the canopy? I saw your pictures on the website. they look good. Just asking how to go about it.
