What a total PITA and waste of time this has turned into

. I like to accomplish things that I set out to do and after 3 trips to area auto stores and about 4 different puller tools, I am still unable to get this HB removed.
Now I will be putting it all back together and hoping it will run long enough to drive it to my mechanic.
If anyone has any insight on removal of the HB from a 1990 Buick Century 6 cyl I would love to know specifically what tool was used.
