Longer wheel studs?

Um, no. The rear wheels don't even come close to hitting the drums. As I stated before , We only need a spacer on the rear to keep the inner section of the TIRE from rubbing on the leaf spring. As far as the front goes, the reason for the spacer is to keep the wheel from rubbing on the caliper. Actually the only place the wheel contacts the caliper is where the center of the wheel is welded to the rim.
It appears these aftermarket wheels are alot thicker where the studs come through. I don't have any stock wheels to compare them to though.
By the way these are 15" wheels. I will do some more measuring of things with/without spacers to see if we all get an answer to this one...
Thanks...Pete

OK, that takes out the taper of the wheel since they are 15" wheels and that ship has sunk. After close examination of the wheel in the picture, you can see the front side is belled compared to the OEM wheel which is flat then a quick taper. The wheels are hitting on the back side of the wheel face, otherwise the wheel still wouldn't go on with the caliper and the spacer off. These are hitting some place and this looks like it.
