Pressure Plate Bolt Application Guide

Combo 1: OEM Dual Mass or Rippie Iron Flywheel with thinner, replacement pressure plate (LT1/4)

How to tell? On the workbench; Place a bolt in the new pressure plate. If the shoulder (disregard the threads) extends through the pressure plate more than 0.090" (3/32") then you have the thinner replacement unit. If shoulder only extends through 0.090" (3/32") then you have the OEM thick unit.

Remedy: Obtain new bolts (6) from GM for LT1/LT4 clutch pressure plate.
