Convert to coil spring or stick with pneumatic?
While this isn't a problem now one of the question marks in the next few months/years is what to do if any of the struts or the compressor go bad (they're fine now btw but are kind of worn). Given how hard it is to find some of the parts, particularly the compressor (which seems impossible), I'm awfully tempted to convert it to coil spring. However, as much as it's practical I try and keep it as close to the original as possible, there's just something not quite right with an H-body that's not pneumatic.
So I'm split on what I should do when the moment of decision arrives and feedback from the wise sages of the forum would be very helpful in making an informed decision.

Rock Auto sell air shocks and air lines for manual filling.
Try "pontiacbonnevilleclub.com" for help, it's a forum that focuses mainly on H and C body cars, Buick, Olds, or Pontiac.

Is that compressor compatible with the original that's currently in there?
EDIT: Running it through the links website's filter the answer appears to be no. I'll post something on that site Rusty Roger linked to.

Well I couldn't get past the registration question on that Bonneville site, but as it happens I might have been able to find a compressor. I've looked for months and couldn't find it and then it just suddenly appeared.

So that begs the question, what advantages would there be to sticking with pneumatic? Would it have better handling or a better quality ride?

Self leveling suspension makes towing easier, and is useful when your wife has been bargain hunting too 
. Seeing as the parts cost very little I would stick with the air shocks. Plus I think the ride is smoother as well.

Well you sold me, in the future I'll stick with the pneumatic. Thanks.

I can't speak to the pros and cons of the factory system ... it's common enough for resto-modders to go from springs to air ride systems that I'd be hard pressed to go the other way. I think if I had to, I'd pull the factory air and install a modern after market air system instead.
