My dad has a older van that everything is falling apart on. The trans was rebuilt about a 100k ago and the engine runs perfect to. I thought I could find a decent 95 somewhere, but they don't seem to be out there on Craigslist etc. Other than the computers and other things that could be switched over is the trans and engine swappable to the 96-2000 years? The 91 has the 3.3 and 4 speed trans. Thanks
