Hey all, I am thinking I am going crazy here, but the two front plugs are slipping on my 13/16 socket I think. Is this possible that they are a different size? I had them replaced last by a well reputed rotary shop, so I assume they are the right kind. Anyone else have a diff. size?

 

it should be 13/16

 

I have pulled mine about 4 times in the last two days...13/16 it is.
