To run the closed composite ball joints #302661 do you need to have these size ball ends
Ball end 4.9mm with thread 8mm for the front #302654
Ball end 4.9mm with thread 6mm for the rear #302653

Tho when you build the kit per manual for eu spec there
14mm screws on the front and 10mm on the rear so im guessing the ball ends they would be the same length.
