The rod is 29 3/4" long overall for a M422A1.
I just measured mine. So, one of yours could be for a M38A1?
It would probably be easier to cut the long one of yours and reweld it than go hunting one down.
Though i haven't tried it yet, I wonder if they are really needed for a top only, without side curtains or doors
. The canvas is held tight front and rear, and the loops on the canvas to the front crossbar keeps the framework from moving ( much
).( I'll probably go home today and try it)
The framework stows quite nicely with those rods removed, and I haven't found a nice place to store them seperately on the Mite.
