The upper control arm snubbers were missing from both sides of my car, I'm guessing this was down to race the car. Do they make a big difference or do I need to find some. How about using shorter ones?

I am replaceing both the lower C/A snubbers as one was worn out

Also, what kind of boot is used on the drag link where it ties to the pittman arm? The old one was FUBAR even though the link itself seems good and tight.
