How crucial are pressure plate locating dowels/pins?

[coheed]

Finally tucking into the AX15 swap for my 3.4 and noticed that the pressure plate I have doesn't have holes for the locating dowel/pins. Looking at other clutch kits that would fit on rockauto some other pressure plates seem like they have holes that would be in the right location, but I don't want to buy a full clutch kit when I'm only going to be using the pressure plate. The pressure plate I have is the only one listed on RA for both the Comanche and the 91 2.8 S10 I'm cobbling parts together for this swap, and looking other places pressure plates by themselves aren't common for this application.

 

All that to say, would the clutch be fine with just the 6 bolts holding the pressure plate in place? I wouldn't think the torque of the 3.4 would be enough to make the pressure plate twist in place, but I don't know.
