Mirrors from other cars on your Mopar?

I can't decide if its the look or the price of a matching right side mirror . I liked the sport mirrors on the 78 aspens but don't know if they will mount in the my 73 duster

Not without a wedge shaped spacer of some kind. The door mounting area is angled down steeply on the Aspen/Volare where its more of a cove on the A body.
