Cool Website, and great information. I'm new to the forum, but have been an old Stovebolt-er for some 17 years now. I've been working on a 50 for several years now and went through the subframe, and extended frame process with it. I'd been thinking about doing the S10 swap on either the 49 3 window or the 54 Panel, and you guys have provoked some thought. Not many around these parts that get this creative to swap experiences with. Thanks again for all your input and look forward to future interaction.
