    5 speed swap will free up some ponies and it sounds like you'll be doing it in the near future. There are a few threads on here how to 5 speed swap. I'm a newb and I did the 5 speed swap in my driveway, I asked questions on TGC when I got stuck. I did all the work by myself, had a friend help when putting the trans back in. Best mod to do. The easiest way to collect the parts is to find a pick N pull junkyard.
