I am most likely going to go with the kit for a couple reasons.
1. I hate wing windows. They are ugly, make noise, and can leak. Obviously the manufacturers have taken notice since nothing comes with wings, and haven't for 15+ years. They finally figured out a wing is an inferior design vs. 1 piece glass.
2. I really prefer the look of the lack of a wing window
3. THe cost of the kit is not a huge deal to me. My 25 year old glass has a couple of scratches, so it needs to be replaced anyway. All new felts, scrapers, and the wing window gasket, and I'm into it them for $250, more if I want to go ahead and just replace the whole wing window assembly.
4. Another factor is the window tint. It's hard to get a good window tint job on those little wings, on both my K5 and K30, I can see film borders on the wings because it's hard to get a perfect cut for them. It would also be cheaper to take my 1 piece glass to a tint guy than it would be to have the wing/window tinted.
I'm basically looking at nearly a $500 split between restoring my wings/glass vs. the 1 piece window kit, I am going to do it.
