I finally got her decently dialed in and it looks like the water isn't leaking into the engine. There is water coming out of the pipes but it is clear water. So things are looking good.
I finalized the purchase of the vintage tube grille. I am excited for it but I'm not a fan of the headlight buckets. It is a sheet of chromed metal and the 5"x7" headlights screw into the metal. No muss, no fuss. The bolt heads are exposed though, not a fan of the look. I believe you used to be able to attach a '76/'77 Monte Carlo headlight bezels to clean it up. Not sure, the bezels aren't cheap.
I am looking forward to get it as it is one of the final period custom pieces for the van. It'll really pull the whole look together.
