Thanks Guys for all the info. I have been on the flywheel with a bar and it didn't move but I will try again. Mystery, Kroil, mixtures of brake fluid and ATF,etc. etc. in the cylinders.
I would like to have it loose before I tear it down and maybe even running if possible as it is complete with carb and all other things necessary. I have it on dollys now but may put it on the floor and try rocking it.
It will be a sweet ride when its done as it is a 5 window with the stainless trim package. I want to try to keep it as orginal as possible..Thanks again. I'll let you all know how it goes....
