adapters

What's up everyone. I'm looking to put dually wheels on my 1500, I really like the look, I don't want the double wheels in the rear tho. My question is using a 5 lug to 8lug adaptor will I be able to run just the outer wheel in the rear? I've got some eBay items, if anyone can check them out...

It's been a while since I've asked.... Anybody running 1/2 wheel spacers on a 4th gen with Chrome clads so they can fit 12+ inch wide tires? Did you have enough meat on your studs? How about 1+ inch wheel adapters? How about longer studers? Need them? For how long? Any issues? Pics?
