Close... almost a sigar
The Continental 60702 is a close fit, but needs an extra slight twist on the radiator side. The length and the other bend look to be a good fit. I have no idea whether my thermostat housing is original. It is aluminum and has a 1.75" neck if that helps any. Can't find any markings on it.
Will see if I have to cut the hose to fit a small section of pipe in to offset the hose for the added twist or if it fits as is, without the hose twisting up. In the second picture I've manipulated the hose to create the extra twist (the first picture is as is)
Looks promising so far.
The lower radiator hose AC Delco 20028S looks to be a proper fit (as is expected)
More to follow, right now it is freezing here.
