That's an interesting point you make, Prop. I have often come across interstitial condensation - to give it its posh name - where it can be a real problem in building construction. Never thought about it in car bodywork though.
Didn't realise that you had done an autobody class. Sounds like an interesting opportunity, even if you were only 6 at the time! LOL
If you referring to the cradle the radiator sits in, the 3 tabs on front and rear are soldered to the radiator. Like me, you can purchase a new cradle, then remove old cradle and fit the new one. It is easy to do, if you can solder.
I purchased my cradle from Kilmartin Automotive Sheetmetal (KAS) in Victoria, Australia.
IMHO the car simply is not worth that kind of money. It could easily swallow up the purchase price (and quite possibly more) in re-restoration costs. The vendor cannot have done his homework as to what the car is worth as it stands. A case of someone chancing his luck methinks.
235-875 looks like a Moss Motors (USA) part number.
If I were you, I'd try to find a pre-owned version.
There were different versions available, but fall into two categories - those that use long bolts or studs, as fitted to the original type housing, and those that have a very thin flange and use much shorter studs.
We were thought in auto body class to apply the bondo on to bright shinny metal with NO rust primer or paint
But that was 35 years ago ...i think the reasoning is the primer /paint provides some kind of ledge that condenstation during radical tempeture changes can attach to that wont occure if its just direct bondo to metal
