I am looking for pics of 90 K5's. I am currently looking at a 90 as well as an 86 (great shape for the year) to buy and am torn between a few of the features. Can anyone help out some? I love the Power rear window, what years had that as an option? I do not like the "fixed" seats in a few that I have tried out. Meaning the seats that do not have the adjustable back piece. What years/models (Silverado, etc) did those come in? If possible, and afordable, what would it toake $$ wise and work wise to repalce them with a new seat, and maybe one that comes with the right arm rest that is on the inside part of the seat? (right side for driver, left for passenger). I think those two (or 3) items are all I am really debating on. Any assistance would be greatly appreciated. Thanks, and I am highly looking forward to becoming part of this awesome group!!!
