hey guys im throwing in a ls crank into my gsr block. When I pulled out the main caps two thrust washer fell out. My question would be should i use ls thrust washer or gs r thrust washer? Or are they the same and it wouldn't matter. Also I believe ls thrust washer is located differently from the gsr washers. I am confused please help me. Anyone???

 

They are exactly the same and in the same location. You can drop the crank right in, just make sure the thrust washers are not damaged

 

THANK YOU THANK YOU THANK YOU!!!

 

All B series mains and thrusts are the same.
