Hello I have a 1973 M400 Dodge executive Motorhome that is in really bad shape celling and sidewall is beyond feasible repair. My question is what parts will interchange on my 1970 M300 with a 413? The radiator looks like it might fit.

I want to grab any parts that might work before we get rid of it for the engine and trans. Anyone need any parts off it?


I'm assuming the 73 has a 440, but if it has a 413 with the big water pump, for sure snag that.


Yup correct it has the 440, it's a big one 29/30 ft.
