57" Ford springs out of an early 90's half ton. They're holding up great and flex really well.
I thought they were Fords, I need to do something softer in the rear of mine and from your pics it looked like yours works well

Out of curiosity, have you ever weighed your rig?
Oh, and one last time....thanks for recommending AFI, we had a trip 2 weeks ago and all I can say is WOW what a difference over the old carb
