Thinkin about it, i'd think the projector bracket must have been preserved otherwise there woukd not be anything to hold the high beam reflector. Would be much more work to make it work. I'm sure you'll find the adjustment screws when you have your car back and have a second look.
Satrya: you mentioned the evo-x R, they are probably similar in size to the rx350 I have retrofitted, and they were quite some work to fit compared to other common retrofit options for bugeyes.
Anybody knows if an oem FX or FX-R retrofit was done on JDM bugeye headlights?
