      Thanks Ken, but what good is a drilled nut if it isn’t orientated the same way your stud is drilled?

      Troy,

      The SKUSA pre-drilled studs, available only at the track (not the online store), are relatively tall with the seal wire hole at the top of them so the seal wire doesn’t go through the stud, only the nut, so orientation is not an issue.

      Follow this link for more info:

      <span style=”color: #444444; font-family: Arial, Helvetica, serif; font-size: 12px; line-height: 21px; background-color: #efefef;”>SKUSA also states that the cylinder length (for a 99) should be 3.11-3.16. Where and how exactly is this measurement taken?</span>

      My observation in past technical tear downs regarding the cylinder height rule, the tech measures the height of the cylinder in multiple locations using a digital caliper.

      Contact SKUSA directly regarding the Head Tech Tool.
