oem wheels.. worth keeping?

[no1udknow]

hey guys. I have a 68 c10 lwb I just got, and after much searching, I found out it has 69-72 k5 oem wheels on it. They are 15x8 grey steel wheels with beauty rings. they are missing the center caps though. I considered finding the center caps, but would need 2 sets of rear caps since my truck is 2wd. On top of that I would need to replace the center "4x4" badge. I am considering getting rid of them since finding 15" street tires is becoming increasingly difficult. I was wondering if they are worth anything or should I just get rid of them?. they would probably be great for someone doing a resto.
