Why do the newbies dig up the old posts?

The OP sold his car way back in 2012 and was looking to buy a Mustang.

Bobby Kelly was banned from this site under four different screen names, for scamming people. Hard to have any respect for someone like that. Similar problems on other sites:

Re: how to Replace your entire opti-spark Unit

I am currently trying to get my water pump off to get to the optispark. Here is a pic of the driver side bolt. I took off the nut, but there appears to be a piece of metal then another nut that is keeping it in. This is the only 1 of the 6 bolts that has this design. Doesn't seem to be like anyone else has described. The piece of metal seems stuck and refuses to move. I am unsure if there is an unknown bolt holding it in place. Anyone else have this problem? Thank you

You have to remove the AIR pump and it's bracket to get to the bolt. The OPs guide is not quite complete.
