Identify Bushing on Clutch Pivot Bracket

[burkeens]

Hope this is the right forum for this question. I am in the middle of having an engine project done (307), and the mechanic is not sure how/where to get a particular bushing. Can anyone make a suggestion -- is such a part still made, or is there some substitute that would do the trick? (See photos.) Thank you.

"Here is the clutch pivot bracket on your motor, I believe there is a nylon bushing that clips on it. The Z-bar slides over it to run the clutch. It is loose with out nylon bushing. The frame side is good, it is the motor side I am concerned with."
