I’ve seen that particular video, and read on another forum (think it was a Dart /Duster forum) of a guy who was making inserts to take up the void, which left some amount of clearance after reassembled, they weren’t entirely solid just some built in lash I think. Made the pieces for a few people and that was it. Guys that have roller blocks sure could use something like that to retain the factory spider and dog bones and save a heap of cash
