Carrier gearshift binds in first gear

[Scrivo18]

Hi

My carrier can get difficult sometimes as well, and a good spray of CRC or similar does wonders, all though one time it was the actually shift pin on the top of the box, a split pin had come out and the pin witch the selectors slide on tried to come out of the top of the box.
As this was Black Saturday and I was trying to get the Bren carrier to the truck and out of the area, I was a little anxious to say the least.
