Bought this flywheel to use on my 2300cc mini stock. Identical to one I'm replacing except for one thing. The flywheel is drilled for the three dowel pins that help locate the pressure plate like my old flywheel, but there were no pins with the kit. Speedway tech said to call Ram, so I did. They told me that this flywheel is drilled for their pressure plate, which takes 3/8 x 16 bolts and dowels are not needed. Luckily, I'm running their pressure plate so no issues. However, if you're running a different pressure plate, verify your bolt spacing and thread size before ordering. Speedway should list this in their description.
