Didn't know which area to post this in, hope this works. I have a 64 C-10 & I am picking up some old 15x8 4WD 6 lug wheels so I can mount some wider rubber on them. Will these accept the 3" trim rings? I also thought it would be nice to put some old rally center caps on(like on a Camaro or Vette)but I dont know if they will work on the 6 lug truck wheels. I also noticed some newer(later 90's-up) Chevy trucks using the 6 lug wheel with a nice chrome center cap but I assume those would be way different....anyone try this or have any suggestions?

thanks
