Bill,
I have a 736 that I thought I didn't need, but according to your chart it indicates that I do. Now I'm confused. My 68 Z has 410 gears and E70-15.

According to my chart attached below it appears that I don't need an adapter. I would like to help you out but I want to make sure I don't need it. Dave

As long as your driven gear is the orange 25 tooth 3860348 is should work according to that 68 chart. The 69 chart I posted says you need the adapter. I never considered the gauge itself differed mechanically between 68 and 69 but maybe that's why the difference in the two charts.

Just found these that I've had squirreled away for quite a while...if they do you any good.
