After going 5 years without wheel opening moldings on my otherwise restored GTX, I finally solved the problem by buying 3 sets at one time from Year One (mfg by who else - Metro). I told them upfront I was going to take the best pieces from each set and return the rest. They had no problem with this. The fit was still lousy, but close enough that I could take them to a good body-man, who tweaked them to fit. Not perfect, but then I don't want to have to wait another 5 years and still be disappointed.
This was the number ONE problem with restoring my GTX.
