WindShield Wiper Arms. Replacement Part?

My Windshield Wiper Arms, are starting to peel & come apart. Does anyone know where I can find a set of replacement Arms, before I buy new wipers and instal them on the old Peeling Arms? Ive also lost the Cap that covers the Nut & Bolt, holding down the wipers.
Side Note: The windshield wipers work perfectly. This is strictly just a cosmetic issue, that drives me nuts. Worst case, Ill sand down the arms, and paint them flat black. And hopefully find a universal cap. Just looking to see if anyone else has run into this issue. Thank you!

I have a 2006 Toyota Tacoma, Pre Runner.

 

I bought a new arm for my 12' and if I remember correctly, it ran me about $50-$60 new. You might be able to find one on Ebay cheaper or even check Amazon....

 

Just take them off, scuff them with a scotch-brite pad, clean them with brake cleaner, and spray paint them.
