OEM Mazda p5 roof rack pads

Hey guys, been trying to look all over the internet for the rubber pads that go between the oem roof rack and the roof. I bought the racks cheap but the only thing that was wrong was that the pad was missing. If anyone has any leads to one, it'd be great. If not i guess i could make one up with a block of rubber, rather get the real part first for optimal fitment, any help would be great! Thanks!
I believe the roof racks in mention are the Canadian version

I've uploaded a picture of what i'm looking for, this is the rear right pad, i'm missing the rear left.

Those roof racks (and the parts for them) are really hard to find. I looked into it a few months ago and phoned my local Mazda dealer (in Canada) with the part number and the racks are no longer available. They don't make them anymore and there aren't any in any warehouse anywhere. He had to phone me back the next day after trying to track them down somewhere.
