I had scoops on rear inner wings so carbs could be adjusted easy and air could get in if interested i will give more info if i can help u
I don't think they're that great on a mileage car, even with a 'filter' of some sort, panels with full closure are OK for access but dont address the air issue. The only solutions that seem to work well and don't create new issues are pretty ugly and aren't applicable to a 'Looker' as such but that's no reason not to use them, just depends on your views on 'form versus function'. On that front you could always glue 'glass scoops to the body and technically speaking "retain the original steel bodywork".
