Installation Notes and Tips

Verify vehicle year, make, model, and front upper position before installation. Inspect adjacent suspension parts, alignment settings, and mounting surfaces during replacement. Because this assembly is non-adjustable, proper fitment and alignment checks are important after installation on 1967-1973 Ford Mustang and 1968-1973 Mercury Cougar applications. The RK621369 part number should be matched to the vehicle’s original suspension configuration before service.
