Correction: having been down this road, for the harrison system you need
air bags with offset fill ports. The ones on the q-bag have the fill in the center.
The equivalent larger bags for the harrison system are: W21-358-7325
Also, all the references I've seen show the Q-bag uses W01-358-7325.
I'm not finding any hits for W01-358-7350 at the various truck spring sites;
not sure it's a valid number.
I see no reason why you can't put two of these on the harrison system to
replace both of the smaller bags he supplied originally. I currently have
the bigger bags only on the mid wheels, but will probably replace the rear
ones too at some point.
