So my new-to-me coach has one new-looking airbag, somehow mounted using the plastic cones even though it seems to have spare metal ones in a box of spares. The airbag on the driver's side is kind of scary looking, very old and cracked, I don't trust it to go anywhere and it needs to be dealt with. The system will leak down if left over a day or so.
I'd love to go all out and get a quad bag system, but I need to keep the budget under control in case more things come up, as I'm sure they will before I take if for it's safety inspection. I still have to figure out the brakes and CV boots and deal with the broken wheel stud, at the very least.
So, do I get one new OE style airbag and maybe cones for the other side? Anybody have one good used OE bag for sale?
Or, should I get a newer system, (I'm slightly leaning towards Daytona Ferrera system) for both sides?
Is it more economical to just get the end-plates shipped and buy the bags locally in Canada? Does anyone do this or is it cheaper/easier to just order everything and have it shipped from the US?

There are good used bags and aluminum cones around from people changing them out for non OEM bag systems. I’d replace the plastic and get one good bag so you can concentrate on all the other issues.

That would certainly be the most economical option for now. I'd like to put off upgrades until I know what else we'll need.
So, does anyone have a bag and cones to sell me? I guess I should put an ad on the Swap Meet list/forum too.

BTW, thought I'd mention I've probably changed more blown airbags than anyone on here.
Where I worked we had a ASRS, Automated Storage and Retrieval System, it stacked 5000lb skids in 8 levels high and 35 long, we had three of them that I worked on.
The skids were lifted off the conveyors for the "stacker" to pick up by inflating airbags very much like the ones on our GMCs. They had to lift up about a foot to clear the forks.
Well, quite often they would blow, you could hear if from the cafeteria, I've been next to them when they blew, loud to put it mildly. Interestingly, I'd never changed the design that looks like the ones on the quad bag or Ferrera system, we used them at one end where they only had to lift 6 inches and they never blew.
In this picture you can see the lift tables near the bottom, one on the right has a skid of rubber on it, the left one is lifted by a pneumatic cylinder as we got tired of changing airbags and eventually modified them to use 14" diameter cylinders.
I don't miss working on that thing, it was dangerous. Had to climb it too many times.
