I pulled my radiator recently and sent it along with a spare from a 74 to the shop . My 71 radiator was leaking. They came back from the shop and when tested the 74 rad was good Went install it yesterday and it is a slightly different size My 71 is shorter as can be seen in the photo. The filler neck is also tilted up rather than flat. The thing that worries me is that when looking for a replacement the replacements are listed as 69-84. That obviously not the case here. I will be returning my 71 rad to the shop to see if it can be repaired. Has anyone else had this issue?
