gday Jump, I got the body and chassis through River Murray Auto Wreckers in SA.
ill inbox you costs etc, but needless to say the cost blew out a fair bit. we got half way through the build and said lets get the truck to a national level so the car cant be used as an excuse for crap performances.

we get them all the time mate.  plus 6 litre engines, and 3.5 v6s.

$ depends on what you want.  obviously the later model you go, generally, the dearer it will be.

shoot me an email with some specifics,   darran@rmaw.com.au ill see what I can do
