I got mine last summer, and they were made just before they were shipped to me, so I'm hoping for the best. Maybe they aren't as warped as I think. I just finished getting my windows in yesterday and the old headliner out. So this week I'll be doing the headliner and the door panels....it's about damn time the thing starts looking like a car, it's been painted for a year and I drove it around with just the front seats in it!
I was doing some reading on Team Camaro, and some guys suggest that if necessary, the vinyl can be carefully peeled back, and the plastic can be trimmed underneath. Also, alot of guys fit the panel to the door, and then create new holes for the clips to line up...that allowed them to fit it between the kick panel and rear seat panel easier.
Sounds like alot of screwing about, but it'll work out in the end I'm sure.
