Just pulled the air bag spring out. At least I had fun...
Bought a Kong red toy in Large and chopped it down to size. Putting a 6"x5/16" bolt through both plates and will install a small Kong toy on the bottom of that so it will keep tension on the fixed plate in both directions (compression and expansion). Hopefully this will be able to handle the rigors of the road.
I will be leaving the Lazy Susan belly off fer now until I can tweak the suspension settings.
