Anybody know what the stock ride height was on a 78 J10?? I'm wondering how much my springs are sagging on my old beast.

The other day the front U-joint hit the starter (Have heavy duty front axle and mini starter).

I could add a block to the rubber stoppers...but that would only leave about 1.5 to 2 inches of travel!!

Thinking of a lift kit right now, but want to know stock bumper height first.
