Like Joe said, if it ain't under warranty, you're probably going to have to pay for replacement out of pocket. That being said, yes, there were two seat belt related recalls for the '89.

One is related to the rear seat belt webbing being a tad too long and I doubt this is really something most folks will get fixed, especially since the impact group is extremely minute. (~35)
Here's the info on the second seat belt related item:
Make : CHEVROLET Model : CAMARO Year : 1989 NHTSA CAMPAIGN ID Number : 90V105000 Recall Date : MAY 04, 1990 Component: SEAT BELTS:FRONT:BUCKLE ASSEMBLY Potential Number Of Units Affected : 1500000 Summary: PLASTIC COMPONENTS OF SEAT BELT BUCKLE ASSEMBLIES DO NOT CONTAIN AN ULTRA VIOLET STABILIZER, AND EXPOSURE TO DIRECT SUNLIGHT AND ELEVATED INTERIOR TEMPERATURES COULD WEAKEN THE PLASTIC COMPONENTS. Consequence: THIS COULD RESULT IN BREAKAGE OF PLASTIC COMPONENTS WHICHCOULD PREVENT BUCKLE FROM LATCHING AND PROTECTING OCCUPANT IN A SUDDEN STOP ORACCIDENT. Remedy: REPLACE OR REPAIR SEAT BELT BUCKLE.
Sorry 'bout the caps, but that's a direct cut and past from the site and I'm not going to take the time to beautify it for you. If you plan to keep driving the vehicle I would do a little research and find out if your buckle has already been replaced. If it has not, I would get it swapped out, but that's just me.
