Mr. G- go with the Mission. It's a far better car according to all the diehard Schuie guys I know.
As far as hopups, get the roll center blocks and the threaded shock bodies. If you're into good hardware, get the titanium screw kit and you won't have to mess with the hoopty wood screws that come with the kit. Also decide if you want to run Schumacher springs or associated TC3 springsd and get them from the beginning. Might consider using the Schumacher nonadjustable shock pistons too. If you're a oneway front diff fan then get one, but I don't see that as a neccessity from the beginning.
Hope this helps!!!
