[AT] Hole in exhaust manifold....

[charlie hill]

Larry I didn't even buy the rods I have.  I was at a boat show with a friend 
of mine who thinks I can fix anything.    He saw those rods and decided I 
had to have them so he bought them and gave them to me.  I went straight 
home.  Got a torch just like the one the guy at the show was using, a coke 
can just like he had, punch, hammer, etc.  I tried repeating what he did 
several times.  I could get the stuff to flow out and puddle over the hole 
but when it cooled I could turn the can upside down and it would fall off 
like it was a coin sitting on the can.

I still have them .................................. somewhere.
