Where can I find the plastic pad for side steps?

[Calvin]

Anyone knows where can I find the plastic pad (the black pad with Mitsu logo) for the side steps? I bought a pair of side steps, one plastic pad missing, recently on eBay. I did not know that until I received it. The seller did not mentioned that in his auction. All he said was GREAT condition. Therefore, I don't care to ask. I will give him negative feedback if he is unable to find one for me because the dealer does not sell that separately. The only fix is to buy a PAIR of brand new one
Anybody has one to donate? What about the auto salvage yard. Where can I find one in the Los Angeles area?
