Windshield Arm replacement

[J&H 49423]

We need to replace both the port and starboard arms on our 2001 380 Sundancer. Having troubles finding the arms. Any guidance would be helpful

I found one at the local PACAR dealer. Had them on the shelf. Mine are mounted to the motor on the frame side and has a screw with acorn nut holding the blade attachment. Exactly the same as on a Peterbilt and Kenworth of the 90's and 2000's.
