Product Description
Genuine OEM 3166936 AMC Rear Cross Member to Sill Cushion (NOS) - 4 Piece Set
This is a genuine NOS (New Old Stock) engine rear support cross member to sill cushion set, manufactured by General Motors for American Motors Corporation (AMC) applications. As indicated on the original factory packaging, this set is correct for the 1963–1966 model years. These high-density rubber insulators are critical for restoring the proper mounting geometry between the rear engine cross member and the vehicle sill/chassis, ensuring correct drivetrain alignment and essential vibration dampening.
This listing includes the four (4) individual pieces exactly as shown in the product photos. This comprehensive kit allows for a complete replacement of the sill cushions on both sides of the chassis. These are factory-correct parts for all 1963–1966 full-sized AMC vehicles (excluding the Rambler American). For enthusiasts performing a high-point concours restoration on a Rambler Classic, Ambassador, or Marlin, these authentic NOS components provide the exact factory fitment and durability that modern universal reproductions cannot match.

A Note on Fitment Accuracy: We research our fitment data using original manufacturer packaging and vintage catalogs.

We kindly ask that you verify your specific crossmember configuration prior to purchase to ensure a perfect fit for your restoration.
Unbeatable Prices & Expectations
While many of our vintage parts were manufactured decades ago, they remain unused and high-quality. Some original boxes may show signs of shelf-wear, such as dust, tape, or surface distress from years of storage. Rest assured, the components inside have been inspected to ensure they are complete and ready to help you finish your project without breaking the bank.
