Try a MOPAR V8 pulley- - - -it looks right in pictures, but I don't have one handy to measure.

You can always turn the pulley 45 degrees and drill any bolt pattern you want if you can find one with the right offset. The center hole can also be drilled or machined to a bigger diameter or a bushing can be fitted to a too-big hole. I've even seen a good welder/machinist make a new center and weld it into a pulley when he needed something that was not available off the shelf.
