I have a brand new Raw Brokerage Crank Collar I'm asking $100 shipped. This is a must for anyone rebuilding any RB with the early style crank collar.
This is what the early style crank collar looks like. Notice how much smaller it is and the damage thats been done to it. It is damaged because it barley makes any contact with the oil pump.
This is the damage that the older style crank collar does to your oil pump. Notice how small of an area it actually makes contact with the oil pump.
The after market crank collar makes better contact with the oil pump and fits a lot tighter.
