Thanks for the reply. Are the parts shown in the photo below still the best answer? If yes, any suggestions on a source for replacements for the black bits? One of mine has the drain elbow solvent welded to it and I very much doubt there’s room to reinstall the the blower assembly with the elbow in place.
It's a shame there isn't a single drain that feeds straight into the factory drain tube that was used by the blower assembly. Perhaps using something like the factory headlamp and taillamp drain tubes.
