I wouldn`t worry about it Jon
. I`ll be looking for a new screen for mine eventually, so it would have been good if I could have used the s13 screen.
Quite a few parts seem to be wider compared to our s12`s, including the bonnet. I`m in the process of modifying the s13 dash to fit my s12 at the moment, just got to change the mounting brackets now, but it does look good on the trial fit. Took me a while to alter it though
.
Regards,
Ian.
