It's not a GTR headlight if it needs a dremel to sit in your R33.
SPDZ1's R33 Series 1 GTR-style housings use the factory hood, fender, and bumper bolt pattern with adjustable brackets built in, so the swap is as-is, no cutting, no spacers, no trip to the hardware store.
Check the bracket spec before you buy any "GTR style" housing online, that's where most of them actually fail.
