Thank you all very much for your experience and taking the time to reply. I will not be out to work on this until Thursday - but I will try to remove the manifold and distributor together and attempt to remove the stubburn dizzy from the back side - as suggested.
I will be posting pictures of it regardless of what happens.
I am going to hop over to the
http://67-72chevytrucks.com/vboard/s...d.php?t=335636 Thread to post pre-project and progress pictures.
Thanks again - and I will let everyone know what happens on Thursday.
