Air Bags don't fit, 1998 Monaco Dynasty

Hopefully, final update on replacing older Monaco airbbags. Monaco tells me that our 1998 was on a Roadmaster chassis and when they went belly up, they gave little info on the older Monacos to the new owners. A great Monaco parts guy has been researching the airbags for hours and says the only one he thinks it could be for the front if a Firestone W01 358-6905. We have ordered them through Firestone in Reno ( $190 each, $45 each shipping) and I will verify that they are the correct ones when we have them installed. God forbid, if you blew an airbag on some of these older units, out on the road, you could be stuck for a long time as the numbers are worn off the parts, and the older Monaco number might not be available, as is the case here. Again, the rear Firestone airbags for our unit are: W 01 358-9376. Hang onto these numbers as our RV is in Freightliner in Avondale, and they took the airbag off, and couldn't even tell what number it was so you have to have this in advance.
Best
