Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Everytime I start a new thread I get told to do a search???? Anyway I found my answer on another forum but I will help out anyone else who stumbles accross this thread. There are 8 bolts total holding the crewman tub there are for in the tub and 4 hidden behind the removable panels inside the tub!
I just finished changing my tub. the four bolts inside are easy to find 17mm socket 2 back ones under grommets, but the other four are actualy behind the plastic moulded wheel tubs you will need to remove the wheels and the plastic inner guard/tub 2 bolts each side run horizontal into chassis also 17mm spanner or socket. The ones behind the inner panels behind the cab don't actualy secure the tub you can leave them in. Don't forget the wiring plug and you also need to take the filler neck breather tube of the top of the filler neck as it goes through a seperate hole in the tub. PS I also learn't not to do it with a chocka fuel tank, filler neck turned and got fuel everywhere. Cheers Dave
