Need 4-speed Help

fstfish66 - Thanks for confirmation on the input shaft. Sorry to be soooo dense, but still don't get the dial indicator measurment process. I understand what you're saying about taking a bolt out, which will allow the dial indicator to attach to the crank @ 90 degrees. What I'm not getting is how you measure if the SS opening is aligned to center? I'm thinking the dial indicator needs to be centered on the crank and then you check the SS openings on each of 4 points to ensure there's an even distance from that point?? Basically measuring equal X and Y axis' are the same from a given point.... That way, it the distance is greater between either up (+) or down (-) (Y-axis) or left (-) to right (+) (X-axis) or a comibination of the 2, you would use offset dowels to even the distances...

Am I completely misunderstanding this???
