radiator question

[3_puppies]

I've got a radiator in the shop and I'm not sure if it's a 55 rad.
my other 55 rads are 24 5/16" center to center on the mounting holes
this other rad is 25 1/2" center to center on the mounting holes
I have a matching fan shroud for it and wondering if it is the rarer 79 version?

If it is a '79 radiator, I have heard they are skinnier...

Skinnier and about an inch wider... sounds like a 79

Thanks for the info. Yes it is skinnier, now I'm wondering where I got it from. It must have been in a parts lot I picked up years ago that had some other 79 bits in it.
