'72 Duster bolt pattern conversion possibilites???

Hi,

New to the forum. We're working on a '72 Duster and have hit a wall, so to speak, in finding any cool aftermarket rims for it due to the 5x4" bolt pattern. Does anyone have any suggestions? We're also considering doing a conversion to a bigger bolt pattern. Has anyone on here ever done that and/or have the list of parts that would work to convert it to a 5x4.5" pattern or something similar? We're wanting to keep it with 14" rims.

Thanks for the help!

Jim
