65 Barracuda daily driver

Here's a couple pics of the same tab on my 66. It curves under and serves as the mount for the radiator.

Thanks @66fyssh! Now I know I'll have to bend it down. I'm not gonna use a stock radiator, so the bracket might be useless, but ok.

Next question:

I'm trying to replace my rear shocks, but one of the upper nuts is on there so tight, I can't get it off. I already ruined it, so I need a new one. It doesn't appear to be stock '65 A-body, but if I can't find a replacement I might have to replace the stud as well. It's 1/2"-20 thread, but I can't find one anywhere.

Anyone know what they're called and where to find one?
