Can you plug the extra hole? can you TIG it shut? Come options.
You say they suck but everything you mention is drill and tap realated. i agree they should have been good out of the box, but they weren't can you fix them, keep 'em. They look bling as hell.
As far as bashing on Pirate, I know as much as they suck and you feel screwed, I think it always (ok, 9 out of 10) looks bad for the basher as well. And depending on kmc's $'s with Lance and Camo it will probably get deleted.
I bought a set of custom steelies for my '58 from a place in Cali called Ralley America. Kid hooked me up on a discount, and sold me good on them. They showed up, all 4 leaked at the plug welds for the centers, and two centers were welded our of center, so they clown car'ed going down the road. It took 6 months and shipping wheels back and forth, but they finally got them right, and made good with throwing in a bunch of other stuff. I coulda bashed them on a board that they are all over, but they literally had tons of positive reviews from customers. They are however just mom and pop and i thought my 1 experience against all the positive ones was the wrong way to go, to light them up in public. They finally made good but was over a 6 month hassle. Some times restraint is the best, we all know on this board, and I know that counts immensly. The mass on PBB, who cares. Just my opinions and experiences.
Maybe KMC will give you an extra set of rings for the future and your hassle.
