Yeah you have all the bits. It's pretty self explanitory. Remove your old stearing wheel and you will find what looks like a big nut. Remove it and put your boss over the steering coloumn, you might need sone wd 40 and a hammer... its a tight fit. Then put the big nut back on over the top of the boss. After that just bolt your wheel to your boss.
i do a good enough job of driving around like a prat anyway , the actual factory fitted steering wheel on the car isn't on straight as it is so anything will be an improvement
