So, has anyone stepped up and completed an airbag system lately.
I'm giving it serious consideration for the big Merc. The existing leaf springs are shagged (and sagged). Travelling to/from the Beach Hop with 4 on board and a boot full of women's clothes the springs are reverse-arched and the rear bumper is seriously low.
Since fixing that will cost some $ anyway, converting to bags is an option, then I could deal with the front as well. The biggest issue is the rear suspension - bag on leaf doesn't look like a good option, so some form of triangulated 4-link (or 3-link) looks like being necessary. I can engineer this myself. On the plus side, I have a York AC compressor and appropriate factory engine mount kicking around already.
Since some of the links in the thread are now old, are there any current recommendations for NZ suppliers of valves etc?
This pic is from a couple of years back, worse now with the new bellflower pipes below the rear quarters.
