---- snipped--- (PS: I thought the new (TC) liner hole size was supposed to be .070", but I'll defer to your measurement)
Steve Chapman had told me that a .073 bit would pass through. I took a #49 bit (.073") and rechecked. It did indeed go through. I'm sorry that it took me so long to get back to you. I appresiate your help with the liner.
