Sorry to jump the thread ... but about the difference from a 2wd Sapp to a 4wd Sapp ... where can I find some info and pic's of this ... also someone tells me that the boot in a 4wd Sapp has a difference compared to a 2wd Sapp

It's just additional strengthening up front, so far as I know the boot is no different, would be no reason so far as I can think as theres nothing different at the back, it's just at the front you have additional stress from the transmission.
Unless of course you mean the remote release of the boot lid itself which 4x4 has?
