Thanx ! .
I was looking in the box of 1964 292 parts this afternoon and found the casted nipple one along with the cast iron thermostat housings upper and lower ~ off to the solvent tank and wire wheel they'll go ! .
Then new paint .
Holding the pump with no nipple nor place to add one , other than that it matches the 292 pump *exactly* , depth , impeller and so on .
I have other queries I'd like you to chime in on and some ring gear teeth and starter pinion Q's too , I'll create a new thread for those .
