Installing CD changer in boot

[almcluskey]

Got a JVC Mp3 changer to install in the boot of my '04 Sporting, have had a look at it earlier today and it seems that the screws will go through the bodywork themselves without drilling, but can't see from the inside of the boot where it'll be safe to screw them through on the wheelarch without hitting any important suspension/brake bits. Is it safe to screw through anywhere on the wheelarch or is there an easy way of finding out where's safe???
