Part Number: TRA-656-639
Install a modern overdrive transmission in your 1964½–1966 Mustang with confidence using our industry-leading tubular transmission crossmember. This USA-made upgrade is the original solution—not to be confused with poor quality copies—and delivers unmatched strength, clean aesthetics, and true bolt-in simplicity.
Key Features & Benefits:
-
Made in the USA – Designed, CNC-bent, and JIG-welded for superior strength and craftsmanship.
-
Original Design – The first of its kind; beware of cheaper imitations.

-
Subframe Reinforcement – Adds uni-body stiffness and reduces flex under load.
-
Powder-Coated Semi-Gloss Black – For long-lasting corrosion resistance and clean appearance.

Why Choose CPC's Crossmember?
While other options on the market may appear similar, most are manufactured with poor tolerances, lower-grade materials, and lack of support for OEM-style insulators. California Pony Cars has been the originator and trusted source for overdrive transmission conversions for more than 35 years.
