Just changed my extractor and downpipe(plue the flex joint) about 2 months ago.
So I have the original GTI parts you're looking for, but your offer price is a bit too low.
PM me with an offer and let's see if we can make a deal ;-)
Guys, To those whom had DIY their own vertical door but do not have good, strong or longer lift absorber to lift up the door, by all means...pm me, thanx.
