They are primary rollers. Just the bushings and washers. I bought the bushings from G-force and pressed them into whatever roller size I am using.What about the Helix?

Here are pictures of the bronze roller bushings after @900 miles. Still tight. They seem to be oilite as there is some substance on the bushing but it does not seem to hinder performance. These bushings are not run of the mill bronze bushings. They are actually bigger on the thrust side as not to be pushed out by the rotational force. The shims are also cut to fit the bigger size of the rotational end. The bushings and the shims are matched.
While I was at it I magna-fluxed my clutch to check for cracks. Happy to say am crack free!!!
