I had time to mount the battery tray from Acme Choppers that my honey gave me.
I took it apart and found center of the mounting bracket.
I figured out how much of the mounting tab I needed to hack off and scribed a line. I used my handy dandy digital caliper I just got from HF.
After figuring clearances of the surroundings I tacked it up.
Ready for finish welding.
Gangsta lean!
