MN_Vette this thread was very helpful for me with the 3rd clutch housing bushing situation. There are some pics and if you follow the link to Omega Machine there's more pics where you can actually see the bushing and it's location so when you're looking into the axle hole with out an axle or possilby the seal removed you can determine better if you should fix yours now. I'll let you know how mine turns out.
