All the clutches we have seen for DSM's are pretty much impossible to have the disk in backwards. The hub will bottom out in the flywheel way before you could ever have the bolts on the pressure plate seated. On another note, have you been replacing the throwout bearing as well so there is not a question there. One other possibility that will make you cringe but is entirely possible. If this is a 1G, the thrust bearing could be far enough off that the clutch wouldn't dissengage. due to excessive crankshaft movement and not enough travel on the throwout bearing to compensate. A 1G could have this problem due to the fact there is no crank sensor to scream about the crank moving excessively. So on that note check the end play. Sorry Peter, you probably should as well.
