May 70 Dearborn Boss 302
The MCA rules, section R, state that the power steering spacer that is between the pump bracket and head is natural Aluminum. All of the ones that I have seen (that I think are original) are steel with what appears to be a black phosphate finish. Also the only repop ones I have seen are steel with black phosphate.
Can someone please confirm what the material and finish is?
Thanks again,
Tony
