Details:
Pictured in the link is a 1969-1970 428 Cobra Jet/SCJ Mustang & Shelby and Boss 429 power steering cooler. Not a repop, but original and lightly used. Paint removed to show the number.
More pics on request.
Looking to trade the C8 for a D0ZA-3D746-A 70 Boss 302 power steering cooler. Same shape as my C8. Not a repop.
