Can anyone tell me what part numbers I should be looking for? It appears all GM torsion bars are used by trucks of all makes/years?

Somewhere I read that OBS 1/2 tons use GL bars? GMPD gives me 3 different part numbers for my truck, but doesn't specify which side or the code:

19330057
19330059
19330060

I've gathered these numbers from browsing forums:

15528965 (LH) GL
15528966 (RH) GL


Any help would be appreciated.

Edit: So I did more digging, and it looks like Suburbans share the torsion bars with 2000-2007 2500/3500s? That sound right?
