Buzz'n,

Both my 15" and 16" rims are riveted (1/2 ton trucks)? Is there a year-difference for riveted vs welded?

The 15" rims have clips for the hubcaps while I have 16" rims with clips and some with no clips (these have a ridge that the hubcap is pushed over).

I assume the clipless rims are from a newer truck?
