I'm at the stage where I would like to remove my motor (253) and gearbox.

I have removed the front guards and radiator support so plenty of access, but I have a couple questions.

1. Should I pull the motor with gearbox attached - would this be easier?
2. How do I do it? haha.

Are there any online documents that could show me how to remove the motor & gearbox?

Also I went looking for the chasis number but didn't know specifically where to look, could someone tell me please?

Thanks.
