Core support mounts?

[rmneder]

Hi,
I have a 72 k10. I'm replacing the radiator and noticed the core support mounts are squished pretty bad. The cab mounts don't look too bad. They are not rotted or squishing out anywhere, but I'm sure they're compressed to some extent. My question is can I replace just the core support mounts without messing anything up. I would replace everything but I really don't want to get into a situation where my hood or doors don't close. I don't know anything about aligning panels and I don't think I would be able to do a good job. I loosened the core support bolts to see if the front clip would come up a little on its own and it didn't. If I can't replace just the core support mounts I think I'll just put it back together as is and when I get a chance I'll take it to a body shop and have them do it. What do you guys think? Thanks in advance for any input.
