I agree with Blas. Call Peter at Nisonger at 914.381.3600 and ask him what kind of deal he can work for you if you send him the broken ones. These guys are not that hard to replace. The hardest part is getting the little screw brackets that hold them in out from the back of the dash. Then you just fish them through the grommets in the firewall and screw them in the manifold and
oil pan. Easy afternoon job.
