Wayment, you trying to go from 36.5 to 31.5? So you need to SHORTEN by 5"? Or did you write that backwards?I'm confusing the shit out myself with the math on this and I want to be absolutely certain before bringing the axle to a machine shop.
I'm going to add 4" to the short side, making the new WMS-WMS width 73.25"
Current spring pad spacing is 36.5. I need the new spring pad spacing to be 31.5, which is obviously a 5" difference.
I don't understand how you make sure the axle is still centered under the truck. Can't move the short side spring pad, so I have to move the long side spring perch inboard 5" to get the 31.5 spring pad spacing. Wouldn't that make the axle stick out an inch more on one side?
Do I need to get 5" added instead?
Help, my head hurts
Yeah 5" is your magic number either way
