ok here we go, some clever man decided to try and open my punto driver door with a screwdriver it didn't work yet that clever fella messed up my dor locks, i've just bought a set from a scrappy including boot passenger and drivers door along with ecu and central locking.

Here comes the tricky part, how do I go about installing them? Anyone know of any tutorials that could help or instructions so I can do it myself as I don't fancy paying £70 to get it done by a garage....

I have a mk1 '98 punto sporting...
