I drilled two holes in the cam degree wheel to install it to the crank pulley. Also found a long bolt and some spacers to attach the pointer, I bent the pointer to make it work this way. I was able to stick an extension and 19mm socket through the center hole to turn the crankshaft. Almost forgot to mention, the bolt holding the pointer on is a thermostat housing bolt for the 4.0 sohc. It was the longest 6mm bolt I could find.
