[QUOTE="husker77, post: 7801040, member: 641116"] for my pair of 15 ti's. Thinking about building this to put in my 91 lesabre daily driver. I know most of you are thinking "he's gotta be full of crap, no way his kid has a 86 s-10 and him a 91 lesabre, no one rolls that deep". But I assure you we have both of those fine automobiles in our fleet. The lesabre has a huge trunk, but to do this I would have to build it in 3 sections and assemble it in the trunk. The sealed sections and the ported section would all be separate, then bolted or screwed together in the trunk. I just kind of like playing around on sketchup, I'm not very good at it but like learning. I wish I could figure out how to move components you import, more practice. I have no idea how good this box would be but I figured it would be a learning experience more than anything.
