airbags that i would need for the 5b? thank you

You have to go under the bus, after blocking it up safely, to look at what you have. There will be model/part numbers on the bag that needs replacing. You can measure also. One of your spares from the PO is likely the one.

The fronts are smaller than the rears on a 5A.  Sounds like you have a spare for the front and rear.

thanks JC.  I think the po had the right airbags, will
do the blocking 4 sure, btw the you have a beautiful
5C,  I have seen the bus you have the po was in E town
a few yrs back and was given the grand tour, was a beauty then.
your a luck man. I never heard or knew it was up 4 sale  i
remember telling the po owner if he ever wanted to sell to give me
a heads ups . but alls good thats life ...Ed

the smaller one is for the front, larger one for the rear.

those are goodyear numbers. MCI # for the front is 12c-1-35, or GMC #2292367 (60.11 ea. @ mohawk)
Rear= MCI # 12c-3-51, or GMC # 2292372 (67.27 ea. @ mohawk)
