Sorry I haven't had any updates with progress. Currently I still have just flat pieces cut out since I'm in my final semester of a RN program and working two jobs. Just missing the two final ingredients to finish, time and cash.
Sorry my drawings don't help you out any for the 2nd Gen aleaddict. I can give you this for recommendation. Go to an appliance store and ask for the biggest card board boxes they'll give you. Then crawl around underneath and use the cardboard to make some initial mock ups. It didn't occur to me to do that until AFTER I had things cut out. I've found that I need to trim an edge on the middle (transmission) skid to keep my tires from rubbing it at full turn right now.
