Swapping pedestals on rallye mirrors?

If you have one, see if the mirrors can be mounted on the side of your door. I have a 72 duster that had the mirrors mounted in the drip rail. I got a set of later A body style and figured I could mount them on the side of the door more towards the front of the door panel. It also looks like either pinto mirrors or mid 70's (puke) bowtie mirrors would work. The problem I have now is that I cut the cables on my remote style mirrors to media blast them up and discovered that I cant find a cable cinch small enough to put em back together.
