trick for installing ignition switch to lock cylinder

is there a trick for installing a new ignition switch into the 85 xjs? there is a small screw on the right side of the lock cylinder, but there isnt near enough room to get a screw driver in there to tighten it down.

are you talking about the actual switch on the back of the barrel,

if so then there are two screws as i recall, on opposite sides , these are very small and tricky to get out, it is however even harder to remove the barrel from the steering column, as there are shear head bolts to contend with to stop removal, i spent many hours with a punch and hammer to drive round the screw heads to replace mine

the main reason for replacing the ignition switch is the breaking off of the two prong fork that interlocks with the switch, this means the key turns but the switch on the back doesnt, so no start of the car , the bad news ( i hope not though ) for you is that your replacing the wrong part if this is the case, as its the actual metal key barrel assembly that is broken ( DAC 4151 ), basically , the two prong fork has failed/broken and will not turn a perfectly good switch . but even worse, this part only comes as a complete section along with new keys and an electrical switch already installed on the back,

it is however possible to by one from a scrapper and install it into your car

a picture of the whole assembly can be seen below ( i hope )

well what i have is a new ignition switch, and all the parts on the lock cylinder, and the ignition switch, are intact and work. i just cant find a way to install the 2 little screws that hold the ignition switch in the lock. any suggestions?
 
Thank you
