Default WANTED: # 3026085 -- 1972 455HO Thermostatic Purge Valve in intake manfold

Anyone happen to have a spare used 1972 455 HO intake manifold valve piece that is pictured they would part with?

And also seeking the part that goes in the passenger side head hole -- a transducer or ?

Anyone know what the part that screws in to the passenger side 7F6 head hole is technically called too?

Is the (70-73) transducer not just a temp gauge sender in the driver side head? So I guess the hole in the other head just gets plugged on the passenger side?

Gets p/n 6490384. Should have connections for both sending units on your harness.

I don’t think I’ve ever seen an NOS one before!

I'm pretty sure those extra arms are to protect the port nipple from breakage, i.e., if the wrench slips while installing it into the manifold port. I have seen many broken ones.
