Upper Control Arm Mount, Early vs. Late

I have 1 1965 barracuda. It has a rusted front frame rail at the upper control arm mount location on the drivers side. All the UCA mount tabs are weak and I need to replace this section. I've found two sources for this part, Rust Repairs and Classic Industries. Rust Repairs states their part only fits 1967 and up. Classic Industries says it fits 1960 and up. Both can't be right. Jerry at Rust Repairs says he "thinks" the first generation were different than the second.

Any clarification between the differences between 1964 through 1966 and 1967 through 1969 upper control arm mounts would be greatly appreciated.
