71 Plymouth valiant.

No,
The one's for '73 swingers are 14.5" long and are more like flat stock with a groove down the length.

Anyways, no worries. I took my round ones (which were 10.5" long) and cut them, added a length of round stock that I sourced from some old bolts, and welded it all together. Looks like I have the round ones but they are the proper length now. So I'm all set.

Thanks!
