[Fot] Extended bottoming tap for TR4 engine

[Bill Tobin]

John, let me look in my collection of stuff; I may have just what you need.
Give me a couple days, I've got some carpenters working in my garage and I 
have stuff everywhere. They will be done tomorrow and I can sort things out 
then. They are putting in a second floor in part of my garage and I'll have 
more room for my stuff.
Now if I just quit buying stuff.............
I'll keep you posted.
Stay warm.
Bill
