Fit a harness bar and belts
1) Remove seats (and the inertia belts at this point if you plan not to keep them).
2) Remove speakers.
3) Remove plastic trim (and the intertia belt spool, if applicable).
4) Loosely screw harness bar in place.
5) Stick masking tape onto the rollover bar at the top and bottom of the circular section of the harness bar where it meets the rollover bar (hard to explain but is very simple).
6) Remove the harness bar.
7) Loosely put the plastic trim in place and, using the masking tape on the rollover bar as a guide, mark the top and bottom of the harness bar onto the plastic trim.
8) Remove the plastic trim and cut away the trim so that it can fit back in place with the harness bar fitted.
9) Put the plastic trim loosely back into the car.
10) Slide one end of the harness bar *past* the fixing point on the rollover bar so that you can then get the other end of the harness bar past the other side of the rollover bar.
11) Bolt the harness bar to the rollover bar. You'll need a 17mm (?) socket/spanner and should be able to pass the socket/spanner through the speaker mounting point in the plastic trim to tighten the bolts. This is a pain in the arse and I sliced my wrists to pieces in the process.
12) Fit the plastic trim properly in place
13) Attach the shoulder harnesses to the harness bar.
14) Attach the lap harnesses to the seats. I removed my inertia reel belts so this was really easy.
15) Put the speakers back in. It's a hassle putting the screws back in because the harness bar is very close to the speakers. I ended up using a very very narrow flatheaded screwdriver at a very jaunty angle to the screw head to do this.
16) Bolt the seats in
