YET another will it fit..... steelies on a 68 Val

I can't really help with what BS would be best for your car. You'll probably have to measure to be sure, since all these old mopars are slightly different. In case you weren't aware, Wheel Vintiques will make a custom offset steelie for you for an extra $25 or so per wheel. I've got custom offset WV steelies on my pile.

Another thing to be aware of is fit of center caps if you plan on running dog dishes with them. My caps wouldn't install on my WV steelies at all. There wasn't much of a retaining lip on the "retaining lugs" to keep them on. I had to do some creative grinding with a small carbide bit and even had to weld on one of the lugs to get them to snap on. Not sure if that's a common issue, but it's something I ran into.

The good thing was the back spacing was right where I needed it and runout was minimal.
