This rubber bushing does double duty, and it does it well. We used to carry both the 701-513-121 bushing and the 411-513-121 bushing, but that just didn't make sense, since they are functionally identical.
Vanagon with cast* lower control arms:
• Upper shock mount (1980-91 2WD/4WD). Two required per vehicle. *If you have stamped lower control arms, you need the 251-411-039 bushings.
• Upper shock mount and rear shock (1993-03). Eight required per vehicle.
