The ax body shells between mk1 and mk2 are essentially the same. Some of the body panels vary (boot and bonnet for example) but the actual shell remains the same and the panels could be swapped around if required.
The main differences between the mk1 and the mk2 is the small updates the mk2 received.
Some weak points in the AX body shell include:
The front and rear jacking point often cave in when jacked incorrectly The boot floor is very thin and prone to rust. The front and and rear wheel arches are prone to rust. The fuel filler surround is prone to rust. The inner arches just behind the headlamps are prone to rust.
