we worked it off from one end. just like the front header SS was clipped on and had to be worked off carefully so that you did not dent the SS. Once it starts to come off, it will seperate. Don't force anything otherwise you will dent something.
I started mine off for the polisher and he continued the seperation. Just relaize that it needs to snap back on when you are done with it. In the case of the polisher, since there were some dents in the SS piece, he had to have it come apart in order to push the dents back out. When he does that he can change out the threaded t studs.
Look closely at it and think front header trim and how did you get that apart.....
replacement piece? you mean the steel insert that has the SS clipped to it? In my case we are bead blasting it and reusing it after we stick the threaded t studs replacements in. If your piece is so far gone, then I suggest calling Glassworks. Seems they have pieces of everything BUT be prepared to pay for it. the pieces they have are originals and USED. I had to get some new hold down brackets for the back window and those were $125 each. They weren't new and they had some scuffs on them, but they will replace the stock pieces......
