Leaf Spring Help

[Sirquag]

Im looking to replace the leaf springs on the rear of my 1980 CJ5 . Found a few things online but I'm wondering if anyone can find the actual length that its suppose to be before i order them. I hand measured one of mine and it was between 45-46 inches eye to eye. Most of what I'm finding online tells me that a 47" should fit mine. Any advice on where to buy would also be appreciated.

The General Spring Company has nice specs for all their springs and how to measure properly.
