Marmoset

Hi all! Recently purchased an 08 1.8 ivtec 5door hatch UK spec and have an issue with the right drivers side window run channel. It has a small nick in it which causes the window to jam. But the biggest issue with this is... Honda have discontinued the part and it seems no where sells it!!! Does anyone has a source for this part? i believe the part number to be 72235-SMG-E01 (but you can correct me on that) Any help from any other owners would be huuugely appreciated! Thanks guys
