Reusing suspension bolts

[jks67ss396]

Guys

Im planning a major suspension rebuild and i wanted to know if its ok to reuse

-the upper control arm bolts that bolt the a arms to the frame... the ones with the teeth in them to keep from rotating..

-the lower control arm u bolts.

-any other hard to find/expensive bolt

Mine appear to be fine.

Ive heard 2 schools of thoughts:
1)the old bolts were much better quality, so reuse what you can
2)the old bolts are 40 years old so replace what you can

thoughts?

thanks guys

I'm rebuilding my front end right now. The upper c/a bolts and lower control arm u bolts I am reusing. top bolts and u bolts I checked no streching or marks on them so I am reusing them. others will say replace the lower u bolts but mine are the larger size used on disc brake systems. I feel confident mine will hold, but on yours its up to you.
