I appreciate all your help and ideas. However, I have 2 drill bits broke off in the bolt holes which no one addressed. How do I get broken bits out of a hole? they are tight, I cannot reach in a 5/16 hole with needle nose, nor can I weld anything to them, nor can I drill them out.
The only other problem at this point is the Gland Pack Nut for the drain pipe. I have heated it so much I believe I welded it to the threads and have broken it off so I cannot weld to it. I am going to try to drill it today with a 3/4" bit. I am sure this will destroy any threads left. Is there a tap this big? Is there an oversized Gland Pack Nut?
