thanx steve

 

The gears have to line up. Try pulling up and turning the distributor back a little bit, and when it gets to where it's stuck, turn it in the direction that it normally spins and it should drop in.

Ps. Make sure the oil pump is lined up as well.

 

That last 1/2" is just the oil pump shaft not lining up. It's not a big problem....just hold steady pressure on it and bump the engine over. It'll drop right in.
