[AT] internal block repair

[John Hall]

George, that is what has already been done. I really like the looks of the 
aftermarket brace. I may make one to install on dads. His has been welded 
for about 4 years and it is a working (yard mowing tractor).  The weld 
hasn't failed but I am with you in that it cannot be as strong as the 
original casting. I have made similar repairs before and added bracing when 
I was done welding.

John
