Body shell questions

[Alexi]

Hi, just a few quick questions regarding my custom XXX-4.

Firstly, when you buy the shell, how much excess lexan do you get? I know that's a really random question, but basically I want to extend the sides straight down, so I can raise the shell by about 15mm. I hope that makes sense, does any one know?

Secondly, does the body shell come with the spur gear cover? If not, where can I get hold of one?

Also, I don't have the slipper clutch tool, can I just use a wrench?

Thanks in advance,
Alexi
