James-

Bending back the support shouldnt be too difficult, but you wont be able to get it perfect. There are special tools made for this sort of thing that body shops have, but i'd imagine you could do a half-assed job with a bfh. It would be a good idea to replace both the upper and lower hoses, and the thermostat when you replace the radiator.

I got your PM, but I dont have any radiators right now. Wish I could help you out.

Hope all is well with you!

Mike
