Years ago I found myself in your place expecting the wrist pin bearings to be in the piston kits. After all, who'd put in all those fresh parts including a new pin w/o a new bearing? Whenever I've bought a Hot Rod or Crankworks crank wrist pin bearings were zip tied to the rod end so I guess that's why companies like Wiseco don't automatically include them with the kit.
Someone should write a book of all the crap that we get schooled on when dealing with these dang Banshees lol.
Anyway - Call Jeff and he'll hook you up right away. I'm surprised that slipped past him as he's usually very good about mentioning any other items that might be needed for our projects.
Good luck with your build.
