David,

Since you have the pan and cap off I see no reason not to set the end float to 
the correct setting.

Just remember when you "grind" the oversize washers down, use a flat surface 
and emery cloth if you do it at home. I use plate glass.
Also make sure you take material off the back of the washer, not the part with 
the oil grove.

But you can have your local machine shop do it.
