Does anyone have the carb float level spec? 1972 Z600.

Hi guys, I'm new on this forum. I have a 1972 Z600 Coupe that I bought new with only 29,000 miles. The car has been off the road since about 1986. I need a set of pinion shaft bushings, Honda part number 53414 538 330. I did a web search but found nothing. I hope someone here has a set lying around ...
