Good To Know

Q: How do I determine if I need offset dowel pins? A: You must measure the bellhousing runout using a dial indicator; if the misalignment exceeds 0.005 inches, offset pins are required to correct it.

Q: Can these pins be adjusted once installed? A: Yes, the offset design allows you to rotate the pins inside the engine block bores to dial in the correct transmission alignment before tightening the bolts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
