Thanks guys. The filling station has a tech article that shows the slot on a 30-33 passenger and tells how to drill out the pin and drive the bushing with a punch through the slot. I assumed they all had a slot . I'm pretty sure the rear is a 37, but not positive. Cast number 377707 on one side, and a 2 on the other. I got feedback from someone that it was a 37. Looks like jim carter may have some new oakie bushings just in for a 37. I will check tomorrow on availability and if they are available, the oKies dimensions.
