OK, folks; maybe someone has found replacements for these, as they are no longer available from Jeep/Mopar:
Part # J3220413 Bushing (#2 in diagram)
Part # J3220125 Bushing (#11 and 13 in diagram)
These retain and provide a pivot-point for the Throttle-Valve linkage from the carburetor to the TF727 transmission. The design of these clips is different from the normal transmission-linkage bushings, as the ends of the rods don't have a groove, but a tapered end that is retained by "fingers" inside the bushing, which makes it act more like a retainer. Without those fingers, that rod would just pop out. If it used a regular transmission-linkage bushing, the nylon step inside the bushing would be compressed by the taper and cause too much friction for the linkage to move freely.
The lower pivot bushing (#2 in diagram) does not have fingers, as it does not retain that shaft, but just serves as a pivot-point.
Is anyone familiar with this type of retainer used in positions #11 and #13? Has anyone found suitable replacements?
