thanks sergef !!
That got me on the right track. Dorman no longer makes the p21c,replaced by 555-086 for the small one 1 3/16 no brass only steel.the larger one 1 3/8 they offer in brass 565-025 just like in your pic. Found both of them in stock at carquest. Still searching for heater hose nipple. Going to design my own and get a bunch milled, just can't decide on billet or brass.Anybody interested??.
