66 valiant A.c. condenser

A friend of mine bought this one new for a 66 and later decided it was too much work to convert his 66 Dart to factory AC like I’m doing with my 65. I bought it thinking I would use it on a 65 Barracuda - which is now long gone. I checked it on my 65 and the mounting brackets are is too wide for the core support; wondering if they changed the core support a bit in 66? Anyway, here it is70C9A7E4-7875-4F9D-BC64-835F0358558D.jpeg

EDIT: I no longer have this condenser as a friend came by and bought it.
