Getting confused

The little boot on the pushrod isn't really needed. I wouldn't lose any sleep over it. Unless you plan on driving in the dust all day long.

Not at all! I think this case has spent enough time driving in the dust and down dirt roads.

Ps I just looked at your car for the first time! Pretty! The yellow is a slick color. There are actually 2 yellow gts cars listed right now (1 is a rotisserie restoration clone)
