Yeah the bodge way to fit this is to drill a countersink in the back of the plate & from the back run a c/s bolt to hold the pillar on using the same thread the bolt from the front does, just make sure both bolts can fit in together.
This becomes a major P.I.T.A. when you go to take it apart though, as they like to spin rather than undo so the wiser make serrations to key the c/s head to the housing.
PS make sure the torque wrench you buy goes low enough. Most auto ones don't.
