Stock leaf spring bushing diameter

I've searched high and low and couldn't find clear info...
What are the correct stock bushing outer diameters for the leaf springs ?

I found something at NAPA, which appears to be the front bushing:

And the OD is 2.5". Some claim the front bushing is 2.5" OD and the rear bushing is 1.75" OD

OME listed the eye diameters as 62mm front (2.44") and the rear as 43.5 mm (1.71"). Close, but no cigar

Does anyone know the diameters off-hand ?

I'm having a set of leaf springs built locally and need to tell the shop the bushing diameters.

Thanks in advance

Well, I got my bushings and they are 2.5" front, 1.75" rear. Case closed

I am looking for the stock ones, and the specs I found are 2" for the rear. But I've also seen 1.70 and 1.75. What gives?

The bushings I have are labeled 52000503 (front, 2.5") and 52000504 (rear, 1.75").
jeep4x4center lists the same part numbers so I assume that's the stock diameter.

And as far as I could measure my old leafs installed, the bushings are also the same diameter.

EDIT: double post, sorry
