Measured the springs today. The 106AA "equivalent" (aftermarket purchased from RockAuto) measured 5/8 inch diameter, while the 105AA (the real deal) measured 19/32 inch diameter... slightly smaller, but measurable.

I'm getting between .572-.585 (rotating my calipers)which which is just under 19/32 so they must be 104AA or 105AA.

This is good news as I really didn't want to lift 4". I have a two door (with a Rally Top shell & removed rear seat) so I could see more than 3" of lift.

On the front I'm debating on replacing the springs. I had an alignment done mid October and the shop said they could not get the camber in spec as the front end has too much sag. It definitely needs from struts as the passenger side is leaking.
