wheel spacers

Has anyone used this manufacturer befor. I just cam across them and they are def. less expensive then the rest. And yes I know "do not go cheap on them" is what alot of people will say. I am just curious on the vender. They use the same 6061-T6 aluminum that every one else uses.

you can get em cheaper on ebay

I have a brand new set that look just like those. They are 1 1/2" wide and i'm pretty sure the bolt pattern is 5 on 4 1/2. They were made by Weird Harold's in Oklahoma. Still in the box sitting on my shelf gathering dust. Send me an email if you're interested.
