E4OD Leak

I have a 1990 2WD 7.3 F350 with a previously rebuilt transmission but I don't know the milage at which it was rebuilt. It has a leak at the rear of the tranny, I have found a replacement seal but, if my research is correct, the problem is usually a bushing in the extension housing which would need to be removed and replaced along with the seal. I have found a new bushing from a couple diffferent online transmission parts dealers and the bushing I have found is a "C-6/E4OD REAR CASE BUSHING W/O GROOVE 66-94" and is only $2-$3. I have read somewhere else that it is a dealer only item. Any info to confirm this would be a big help, this should be the last of my repairs to get this truck back on the road. Thanks!

That sounds like it'd be teh one. I'd make sure it mentions that seal for a 2wd tho. different tailshaft housing for 4wd prolly has different bushing.
