Andy, for your B44 I would use some RPM Long Shank Heavy Duty Rod Ends, such as these here

They will not pop off quite as easily as the standard AE ones. Although having said that, I raced most of the B final on Friday with only one rear camber link in, as it got bashed off
Good to hear that both you and your son enjoyed the night
