The Eldo wasn't unique so any 472-500-425 and maybe 368 should work. 

I believe the stat diameter and bolt spacing was pretty standard for classic American engines so its mostly the hose diameter and angle.

good used are readily available, and should not hurt too bad on shipping - how is it that this cast iron piece needs to be replaced anyway?

It is a tin piece, so probably rusted out.

Trevor,

I should have one down here if you can't locate one closer.   I will dig it out and see what condition it is in.

The 429 engines use an aluminum thermostat housing to connect the upper radiator hose to and those suffer galvanic corrosion.  My 1970 thermostat housing (472 RWD) is cast iron.   Guess in 71 they went to a different metal.

I think that the trouble with a cast iron part in such a small configuration of the design would snap off the ears when constantly being tightened.

Steel will just bend a bit.   Plus, cheaper to make.

The original cast iron ones from 1968-70 can get crusty if neglected. Mine is showing its age, but at least its not leaking yet.

I also noticed that there is an ACDELCO  replacement part that is good for several years, but itis stamped steel (painted black) and I'm not sure how long one of those would last. And now I can't find it. You'll probably have to peruse fleabay for a decent used one.

^^ Do you see how the fitting is necked down? This might not be good for the 500s & 472s.
