They are sometimes given for free with the battery if you buy that battery at a GM dealer; they are not expensive separately at a GM dealer although there is a likelihood they won't have it in stock; 25720111 fits the 99 Riv's standard battery. 95-97 it's 25678807. 25678809 is for 98.
HOWEVER - the batteries are somewhat interchangeable as they all fit in the same battery tray/clamp for all years. They batteries just differed in the spec for CA/CCAs.
SO -- what you actually do is just get the vent tube for the battery you buy, which will likely be the 99 spec, which means you go get a 25720111. I think it will run you between $16.- and $30.- at a GM dealer... which is one good reason to just buy the battery at the dealer (for some reason dealer pricing on them is quite competitive) and let them (if you have to just ask them to) throw in a vent assembly that fits the battery you buy.
WHAT TO DO - check your battery voltage with car off and battery disconnected. If voltage is below 12.4v, charge the battery .. If after charging it stays at 12.4 or less, consider replacing it (it should be 12.6 - 13.2). Why? Because the Riv has a high parasitic drain and acts funny with a weak but serviceable battery. When you get a replacement for any Riv most likely the GM dealer would sell you the '99 spec battery, 840 CCA. The earlier year CCA specs were higher, like 970 I think.
