The morette twin lamps look good on a mk4 as they look like part of the bodywork, but on a mk3, well they just look like those silly stick on things!
Another idea for you, how about painting those RS turbo doglegs black? Went mk3 hunting around the scrappies today, didnt find much, but in one the was a silver B reg ghia, quite tidy but bin scrapped as it was too old ( waste!) anyway theres also a series two RS turbo in there with black doglegs, put one of em up against the ghia and it looked well nice!
