years ago, i bought six outside handles at carlisle for $5.00
they are very similar to what you used, but they are for the same side. this means the lock cylinder will be forward on one door, while being rearward on the other.
i never looked up the part number, but it is 04719421, and there is a date number of 3110-1/95 on the boxes.
these handles are square edged rectangular units, and are very thin, so they will work great for outside handles on my humpback project. i already have inside "backers" made for the doors to stiffen the inside of the door skin, and these will butt under the outside character line of the body, becoming almost invisible with the body's patina.
i know some would want this thing painted, but #1, i won't live long enough to do so,and #2, i'm not a body man by any stretch of the imagination.
