if externally balanced then the balancer will have a significant weght on the inside of the wheel, on the motor side. You could just buy a tape stip from summit racing to stick the degrees onto the balancer.
If you have yours pulled off, and it is external, do me a favor and measure the length of the spindle that goes over the crank shaft, th full length. I had mine machined to shorten by 1/8th of an inch, but I forgot to measure before giving to the machine shop and now I need a way to validate.
Enjoy, KC
