thats not an rs turbo spoiler whole pattern, as both the 90 spec and 88 spec have wholes in the centre aswell,
and the wholes for the rs turbo spipolers are closer to the outside of the boot.
that whole patter looks like it might have belonged to one of those shity 1.3 bonus spiolers.
ull propbably have more luck fitting a 88spec to that boot, the 90 spec prob wont cover ur existing whols.
hpoe this helps
