Update time: First fitting continued. To date, I've fit the rocker panel, floorpan, underfloor brace and park brake pedal assembly (w/brackets). In the pics below you can see most of it. I've started holding things in place with sheet metal screws, while I adjust each piece to get a good fit. This isn't the permanent screw down for welding, as I've still got a small amount of rust to cut out and make the final trimming of the new floor. Plus, I need to make a small patch to repair the seat riser where it meets the floor and weld that in place before finalizing. All in all, though, I couldn't be happier with how its turning out. I hope to have everything that I mentioned above finalized by next week and maybe even start welding it all in place. The cold weather "working on my truck" season is rapidly getting away from me. Got to keep moving! It does seem like my goal of getting the driver side completed before the summer season arrives is a long shot....
