Did not realize I needed a different sized top hose with this radiator. You think I can stretch/reshape it with a lighter as a VERY temporary fix? Or is that as dumb as it sounds?

If I had done the coolant reroute at the same time it would have been fine, I have the hoses for that. But I was going to save that for another free day and just throw in the radiator and overflow tank today. Last resort is get a tow back home (I'm at an empty business park) but I reaaaaally don't want to do that
