71 shortbed swb factory height

[redbowtie74]

I just picked up a 71 swb and I like the height the previous owner has it at, they just went about the wrong way and just cut the springs so im trying to determine what the factory frame height is or ground to fender lip is so I can determine how much lower it is now then factory so I can order the parts to lower it the right way, ive searched without any luck so far

thanks
