GQ shortie CHOP

[brw1994]

Hi guys anybody know of "How To" thread on "chopping" the back end off a GQ shortie?
I've searched and only get rear quarter chop related stuff :/
In the UK we call it "bob tailing" but seems to be different lingo in Aus ?
I've bashed the back end of mine again this weekend so willl now be defo cutting it's fat arse down to size, any help much appreciated

I don't know if this is not acceptable but I know that patrol4x4.com has a lot of chop threads for ute convertions etc
