I’ve got a 1966 FJ40 with front wheel cylinders that have been leaking for years. I cleaned off all the built up crap and I don’t think I can rebuild these cylinders. I’ve got some cylinders from a 73 that I could probably rebuild, but I don’t know if I can use these on a 66 or which ones go on each side of the front wheels. Based on what I’ve seen on CCOT and other sites it seems like there are specific cylinders for the left and right side of the vehicle, and left and right side of each wheel. Anyone ever swapped cylinders before or know how to tell which ones go on which wheel?
