    This is a old thread, they probably won’t reply. I’m about to build one of these myself and have the same question, when I get my cylinder kit later this week I’ll take the measurements and link one. From what I know you do not want the self lubricating style because they will wear quicker.

    Okay so the bushings you will have to find some on your own that dont have the self lubricated coating like mine where. I had to tear mine down and found that the bushing was showing decent wear and looked like the wrist pin got very hot. The wrist pin turned blue around the bushing area lol. Maybe it will help to drill relief holes so it can get some oil. I'm not sure

    Bottom line is it needs to be 100% brass and I haven't found one. Ebay might be your best bet

    Here are the bushings I bought

    I found some brass ones in a giffy

    Search those dimensions and you'll find what your looking for.

    Good luck with the builds!
