not verbatim but wes (thatk30guy) told me the 203 is very heavy sould look like its two peices, has an aluminum rear output slip yoke, the 205 is lighter (you could brob lift it but dont recommend) its one peice, from what i've noticed at the end of the shift lever it has 2 "prongs" going into the case some have slip yoke and some have fixed yoke. thats about all i can tell you
