How about a hose with the correct ends? A good auto parts store should be able to find something that works. Plus, a hose clamp can squeeze it down far enough to get you to the store. Or a piece of smaller hose inside your larger hose, but that's kinda the half-assed way I used to do things!!

since erics an idiot and doesn't respond to his post replies (why post in the first place douche:devil:)...

the end on the stat housing is normal size but for some reason the radiator inlet is really small, the next size down hose might work, but thought there may be a proper adapter style deal for it...*haven't looked online yet:rolleyes:*

Sounds like your radiator wasn't made for a third gen Nova. Several GM vehicles built in the 80's had a radiator with all the same physical dimensions of the factory third gen radiator. The only difference was the upper radiator hose size (and sometimes an extra heater hose connection on the passenger side radiator tank).

I seem to recall there being a different thermostat housing on the market that is the correct size to match that radiator.
