What years of power steering will fit a 64 A body?

Jake - on my 65 PS box, it takes a 5/8 return hose as does my pump and a 65 Imperial PS cooler I have - don’t think it’s 1/2 inch. I think the later stuff uses the 3/8 but since I’m not that familiar with 67-later I may be wrong.
Don, I’m sure that you’re right. I thought it was big but didn’t think that much. The later version is 3/8 for sure.
