Here for your consideration is the very nice original used condition 1972-74 style Plymouth Barracuda / Cuda inside door mounted door window regulator arm pivot support and guide piece.  This is shown in the Chrysler Parts Catalog as being their part # 3417250.  Shown as being the same part number (will fit) on either side door.   I believe this particular one was originally off a 1973- era Plymouth Cuda right door, but again,  believe used on various 1972-74 Barracuda / Cuda, and listed as same for both left and right doors, but this 1972-74 style one here is slightly narrower / thinner width bracket than early year Barracuda / Cuda ones, and possibly shorter overall too. Same 8" center to center of mounting holes as early- style  (narrower) Barracuda / Cuda ones however, so may work on 1970-71 Barracuda / Cudas, but please do your own comparison, measurements, and research if wanting to put this on them.  Comes with the correct original nice condition used mounting bolts, to hold it to the inside sheet metal of door.  Has pretty nice clean original galvanized plating still, and is not badly rusted, pitted, damaged, or worn at all.  Looks nice and has been stored away inside on the shelf here for many years, keeping it very clean as many of these go.  This measures approx. 8-3/4" overall length, with center to center of mounting bolts being 7-7/8" apart, and the width of the horizontal channel that regulator slides in is approx. 3-1/2".   The main body width of this narrow style 1973-style support is approx. 2-1/4" wide, where early- style (think 1970-71? era) Barracuda / Cuda ones of these were 2-3/4" side to side I believe  (see last four pictures with tape ruler in them here).  

Please note this piece is NOT the same as for 1970-74 Dodge Challenger models, that had a slightly different size, and wider width (about 5") for the horizontal channel for window regulator slide.  If you need one like this for a 1970-74 era Dodge Challenger, please check another of my listings, as I have a nice one listed for them too.  Thanks for stopping in to look and bid!
