Problem is getting one made for each specific crank and fit needs to be about perfect.
Also can have clearance problems to the splines on the input.
I tried a bushing from speedway once that has a shoulder for extra height with a motor plate. It spun loose after very few runs.
I have a torrington type bearing here from moroso goes in stock pilot hole.
Anyone use these? Believe this is used in some oem applications.

The sealed bearing is best, but you have to have it set when the crank is out. I have used the needle bearing bushing in stockers but they do wear out. I have also used the Kevlar ones in a pinch.
The modern clutches we all use put more strain on the pilot bearings so anything other than a good strong roller bearing is going to get wobbled out and can cause issues. Thst is ok as long as you keep an eye on it and are prepared to change them as needed.
