Hey Baldone,

Here is the link to the [link=http://www.cenracing.com/downloads/difflock.jpg]GST Diff Lock Instructions[/link] Now keep in mind these instructions assume you already have the diff out of the tranny. Also, be very patient, and use a good hex driver and plenty of heat on the diff to soften the Locktite used at the factory during assembly. Be careful the diff will be hot while you do this so be sure to use a rag or hot mit or heat safe gloves.
