You can get them at YearOne or any of those places, but I got mine through a body shop in town that does collision repair. If you have one in town, maybe give them a try.
I bought full chrome units at my local good old boy hardware store near me. They were $3.00 a piece but were not capped chrome like most places!! Rolisons hardware in Brighton Michigan is where I got them!!
Yep.....went to the local farm store, Big R and they had them. No chrome or stainless but a bit of time with a dremel and polishing compound and they looked just fine...
What ever you do DONT BUY ONLINE! It will cost you way more to buy online, find a hardware store or a store that really only deals in fasteners and what not, I took some time and found them way way cheaper through a local shop in Detroit.
