1964-1973 Upper Control Arm Grease Fitting Kit, includes 4 Zirk Fittings & Instructions

Why Proper Lubrication Matters
Getting a grease gun onto a classic Mustang's upper “A” arm is difficult—even with a standard 90° grease fitting. The challenge is especially tough on 1967–1968 Mustangs, where there's not enough clearance for conventional fittings. Without proper lubrication, upper control arms can dry out and seize, increasing stress on the shock towers and causing cracks around the “A” arm bolt holes.

This damage is severe, expensive, and often leads to complete shock tower replacement. Many owners who skip proper lubrication end up with costly repairs—and wish they had installed a proper Mustang upper control arm grease fitting kit sooner.
