Jerry says The original part was cast from pot metal which corroded and was easily broken off in the thermostat housing.

It would be very wise if "all" owners actually checked that fitting when doing maintenance or if you don't remember ever checking, do it! The early production fitting was used in most GM's of the time and the material actually swelled and became fatigued. It wasn't uncommon to have these fail on any GM that used them.

I don't know how you would remove the threaded aspect of the nipple in the ZR-1 short of removing the t-stat housing and doing it on the bench. I've never needed to so.

Jerry of course has them but if you were in dire need it should be "on the shelf" at most GM dealers, ACD jobbers and most auto parts stores. The service part is certainly the more desired product!

If you can't get a 1 1/16 (27mm) end wrench on it you need to be concerned. The OE is only similar to Cliff's image but Cliff's is what the later "service part" would appear as.

THATS IT!!!!!! very brittle however I have everything apart may as well pull the housing out and see if I can get the leftover out,Im sure by its weakness it would have let go.
