This is what I was thinking for the limit straps.
I tried some exhaust clamps at the bottom, but they're too short. I'll have to fabricate a couple. I was thinking that this clamp can be slid up the axle to adjust the tension on the strap, then clamped down to secure it so it doesn't move. When I fabricate the new clamps, I'll probably allow some room for some rubber between the clamp and axle. I don't know if this is needed or not. The top strap attachment might also need to be bent slightly so the strap doesn't rub the shock spring.
We have a term at the shop, ABT, always be tweaking.
