Find the two plastic caps sitting behind the sun visor on either side of the car. Gently prise them out, be careful as years of sun may have made them brittle. Behind the caps you should see a hexagonal head that the manual roof tool fits into (failing that use an allen key). Turning these hex heads will unlock the front soft top locks. (can't recall if it was clockwise or anti-clockwise, so be careful!). I found that you need to start one side, then unlock the other side, then come back to the first side and finish the job off. At this stage you should be able to lift the top up slightly to see it's no longer engaged in the front locks. Now move to the boot.

In the back of the boot you should see two small pieces of the trim that will lift out. These will be located on each side near the boot hinge mechanisms. Lift the trim peices out and you should see a lever (mine is made from cad plated something or other, ie it's a gold colour) and it will have red paint on it.

Fit the spanner/wrench end of the manual roof tool, or otherwise a 10mm open ended spanner, onto the small nut welded into the end of that red lever. I started on the left side(passenger side), levering gently down will unlock, and gently up will lock). You may need to alternate between each side, undoing a little and then swapping. NOTE: I found the levers won't budge unless the soft or hard top 'pins' are physically sitting in the lock holes. Don't force the levers as they should move quite easily.

Now that you have both the front and back locks undone, the last part is to unlock the tonneau or rear deck (soft top roof compartment). To do this you need the 10mm spanner/wrench again. You will find two hex heads tucked down in between the roll bar and the side of the interior trim (about 6-8 inches from the door frames), fit the spanner onto the head and turn until the tonneau cover releases. You should now be able to fold the soft top down by first raising the rear section of the soft top until the back lip is pointing to the sky, then lift the front section along with the rear section down into the compartment. I guess getting it back out is a reverse of the procedure above. Hoepfully I've got it all right as I've done it from memory.
A part of the mechinical components that operate the foor is sticking, have some one try to open it whilc you examine and see there this clicking sound(something slipping) is comping from, more than likely is a gear or a component that turns or wroks with motion.
