No worries man. There is an online version of the manual here -> https://www.300zx-twinturbo.com/cgi-bin/manual.cgi
It's also available in the google playstore for android. https://play.google.com/store/apps/details?id=co.fixitfixit.z32
There are also some PDFs available from here -> http://www.xenonzcar.com/z32/fsm.php
It's all more or less the same thing. I prefer using the PDF, but the android one is handy when I'm in the garage.
