I saw a mk3.5 with these bezels fitted a few weeks ago and was really taken by the factory fit look and how they enhanced the front of the car. I ordered a pair from MX5 Parts and they arrived in two days.
After cleaning the existing area that the bezel would cover I followed a tip in a previous review and added a bead of mastic near the leading edge two-sided tape on the rear and fitted the bezels. (I suspect that the two-sided tape would have done the job on its own).
I am very pleased with the fit and the appearance of these bezel’s and have already encouraged another owner to buy a pair.
