That kit is definitely short 4 o rings, and I think it is the same one FCP sells, which did not have all the ones we needed on our 99.

If you take the old one in to a NAPA they should be able to match them. There really isn't anything special about them so long as they are rated for PAG oil and pretty much all of them are.

Old thread , adding knowledge

HNBR are the type of orings you want to use on air conditioning systems with PAG oil
