What is the size, gauge, etc. of the cb750 frame? As I mentioned in a previous post a while back the PO lopped off the left frame ear so now I'm trying to find an alternative to weld on so I can mount passenger pegs and go two up. I'm thinking if I can find the right steel tubing I can weld it on and paint it flat black like the rest of the frame. Bike is a K6 but I'm assuming the frame remained the same from 69-78.
