CB350 frame work

This frame has been brewing in my mind for a while now. Tim brought the complete bike to me with the request for me to hardtail it and try to replace the backbone so he could run a narrower tunneled tank on it. These frames are tricky because the neck, backbone, and seat tube area are formed from stamped halves that are spot welded together. The traditional frame mods wouldn't work, so I decided to cut into the backbone and massage it a bit so I could slide a bent piece of 1 1/2" dom into the "saddle" area the cutout created. I've included a pic of the shit show welding job a previous owner performed on the awesome struts welded to the swingarm.
