Thanks Bob & Co.!
I also have the Moss H/Duty gasket. I only asked the list about
planing, as I only want to do this once.
You know how it goes, I need to rebuild my carbs., while the carbs are
out, I'll replace my choke cables & clean up my manifolds, while the
exhaust is dropped, I'll do my universal joints, while my drive shaft
is out, I'll regrease it. Now I can get a good shot at my inner wheel
wells, I might as well paint those.
Before you know it, I do not want to fix anything, as it is time to
drive it! As I saw on the list & laughed, "It is definitely time to "UP"
the medication"
Bob, It's all your fault! See what your Carb rebuild tech session
started! :-)
Thanks to all, The list is the "Balls" If there is a clothing list out
there? DO NOT!!! Tell my wife!!!
