JK *front* spring diameters?

[Caver Dave]

Wondering if someone knows (or could measure) the top & bottom OD on a JK coil?

Some interweb sources say they're the same as TJ/XJ? (but don't trust kids that call their Jeeps a "car")

They might not be the exact same but they will interchange. I have an LJ at the shop with JK front coils in it right now.
