I'm stripping an S model right now and with the limited availability of 1st gen parts, as well as the dated appearance of the plastics, I'm thinking about swapping out the tail as well. My first thought is just a 2nd gen swap, but everywhere I search for info, I get the same useless non answer. I know somebody has tried something at some point, but I'm not getting anything with the keywords I'm using. I'd like to walk into this with a little knowledge before I start buying up random parts to see what's what. I think the tank has enough of a modern design that it'll blend nicely with a next gen tail, but I might look into a tank swap as well, depending on its fit.
