I have a hydraulic cylinder for my tilt. It has a 1" swivel end and my bolt is 3/4". I can't find a 1" to 3/4" reducer.
I would even buy a new top link bolt that had a 1" end as another option.
I had the same problem and found a bushing at Tractor Supply Company. I think they would be available at most any farm supply store. Less than $5.00 for a pair.
