67/8 tear down

[low&slow]

Heys guys I'm new to the 67/8 c10 trucks. I've owned and worked on my other past trucks that were 69-72 c10's. I got a whole front clip pieced together a couple of months ago. There's a truck not far from me that has good chrome rings and bezels. I know in order to get the chrome bezels off there is 4 screws. Now as far as the middle ovals go, how do those come off?

I'd just like to be prepared before I go out there.

The truck I'm getting them off is a 67 c10 longbed big back window. 100% original. The owner told me 6 yrs ago that he was going to restore it one day when I offered him $6,000 cash. He knows I've been scoping it out since then. He finally told me I could have SOME parts off of it, like the parts that will get replaced. So I'm starting with the small pieces and later I'll work up to the big pieces till one day I have the whole truck....Well that's the plan at least
