The direct clutch sealing rings are available in two thicknesses. 1985-92 models use rings that are .083" in thickness. The 1993-95 ring is .102" thick.
Due to the change in ring thickness, the groove in the center support was changed. The support that uses the .083" ring has a groove that is 105" wide. The support that uses the .102" ring has a groove that is .120" wide.
