bump. i'm crawling out of my cave if you even remember me i gotta say that you and I are alot alike in our OCD for the details on building a crew cab. I've always dreamed about building a crew cab too but it'll prob realistically never happen for me. I'm happy to see you doing this and its awesome to see your idea of using an ex cab. that's an idea, like everyone else, i never thought of. the window channels have always been the kicker on the conversion for me. I've never been a fan of the different width doors in the 4 door blazers. hopefully the progress gets rolling again soon but what can i say, i haven't touched my truck in over 4 years..... unless you count stacking storage bins in the bed so why exactly did you move to Michigan and back again? i missed that part.
