Can anyone help please? 93WRX Saloon
The left roof strip that runs up the side of the windscreen, along the roof and down the back windscreen is loose.
It doesn't seem to fit in quite right, the plastic clips under the windscreen don't hold properly and likewise the ones under the rear window. If i push them in another bit pos out.
Some of the plastic clips on the roof are broken and a couple of the mounting points have pulled off of he roof altogether and may need welding back on. I think that with these clips off the rest of it won't go back in.
Has anyone experianced this and has advice to sort it out?
The strip on the right side is fine.
Many thanks, Matt
