I used to screw around with a 1/4" drive, deep well, 5/16" socket and extension trying to get the
oil pump shaft in a position to just pop the dist in but what a pain in the azz that can be. If the only thing holding you up is getting the dist shaft aligned with the op drive shaft then you can use this trick. Since you've gone as far as removing the dist then I'm assuming that you probably have a remote starter switch and know how to hook it up and use it. With that switch in one hand, place a bit of downward pressure on the dist body with the other hand and bump the starter. If you already have the dist gear teeth meshed in the right location then the dist will pop the rest of the way down within about 1/4 of a crank rotation. Now I didn’t say some things that many take for granted as things that you do every time you are working on the engine like: Trans out of gear, wheels blocked, coil wire near some ground (like a valve cover), don’t grab the rotor while bumping the starter, etc. so just be safe about it and that one little trick can save a lot of heart ache.
