Hi Mike, I looked at the post and the tank bolt frame mount looks like a pretty simple solution. Also, I cringe whenever someone says I didn't return an email, don't get me wrong I screw up more than most, so I went back and found your email and my reply from 11/12 and forwarded it on to you. Sometimes hotmail accounts go to spam, but give a check.
Here are some shots of the design I have, this along with the frame mt could solve it. It's tight between the lower clamps and they'll need some cutouts to fit, but this will get it mounted up.
Let me know what you think. Paul
