WA WTB DG4 Mirror or parts

[nitrosport_5]

I am looking specifically for the part of the DG4 mirrors that is the curved tube that bolts direct to the mirror head an curves down to the brackets that bolt to the door. I have 3 sets of these mirrors, but they all seem to be missmatched. I have 3 of these that are chromed steel, 2 that are annodized aluminum and 1 that is stainless. I am looking to buy 1 that is stainless to polish up and match the rest of the arms. will trade for the aluminum pair if interested or will buy outright. WOuld buy a single or full set of mirrors if i had to to get the one arm. let me know what you have. thanks in advance!
