Well, thank you for your ironic help Believe me, i did search and i have found this thread. I have found it yesterday
night, because then i finished with the rebuild of a completely new body... It was my mistake, because i tightened the screws too much, and i also applied screw tightener that helped in the plastic weakening and the arms have cracked (3 of 4)... Well, i don't have to explain to you my reaction, so please understand me, that i only had a few minutes time at work today to post two questions on the forum. Believe me, i was aware about the search Now i got home, a few hours ago, but i had other things to do and i was after my wife with the car, so i haven't had so much time... Anyway, thank you for your ironic and "crude" answer.
