They came in 14x6 and 15x6. You will not find 8 inchers. You can find 'em on ebay by searching under "Ranger Wheels" Mine are all gunchy from the winters up here, so I have searched for 'em in the past. There are usually some on ebay, if not today, then next week.
if you want some in 8inch youll have to take a set to a wheel repair shop to have them widened. stockton wheel I believe does it, as well as a few others.
they look to have all the backspacing in the back of the wheel need to check backspacing with 8"with a slick
I have 2 of these but no the same centers as you. Id be willing to let go of http://mmb.maverick.to/attachment.php?attachmentid=8001&stc=1&thumb=1 The centes I have screw into the wheels. Not shown in that picture They were cleaned up and painted aluminum to match the wheels (chrome was flaking) PM me if your interested
Yup, i seen it at the bottom of another thread. in the "related thread" section Thought Id see if he still wants them. haha
Might as well update. I found a set of 4 on one of the boards that the guy gave to me for the price if shipping, about $85. If you're patient, you can find some...
