I bought some 17x8 Edelbrock 454 wheels and hit similar problems. They had tri-bar spinners that actually screwed onto the push-in center cap. The center cap wouldn't fit over the hub, just like the coy's. I also had a problem of the lug recesses on the face of the wheel. The only thing I can figure is the 5x5 cars must have smaller lugs, because there was no way I could fit a lug nut in the recess.

I wound up going with 17x8 American Racing Torq-thrust Originals. They bolted right up without any problems.
