air bag replacement - dual convoluted or rolling lobe?

[Chopper Scott]

The problem with using so called over the shelf bags is their size. The original bags in the front of the bus are fairly small and short. I could see someone altering the top support that comes down from the beam to allow more room however. But still you would face a problem with the larger circumference around the axle mounts. The rear bags are larger and I haven't tackled that change yet. I'm still waiting on a back ordered bag.

I was wondering if someone with a block off plate to rolling lobe conversion (MCI as well as GMC) could post the air bag part #s.  This would help me source bits up here in snow country.  The steel bits would help as well.  Basically all info possible re the Mohawk system.  The OE double convoluted bag part # as well to help me compare apples to oranges etc...  My bags are OK but I already have one block off plate and I see more in my future.
