I will actually disagree with Dude on this.. it was my understanding that the Lucas and Trico twin blades were offered for the MKIA Tiger and MKII... I dont have a copy of the BON but it lists them in there and from which cars they were used. Perhaps they were also called "aeramic" blades
I had 2 sets NOS in the boxes, sold one set for $35 without realising what they were (was hunting correct series 3 trico rainbow heads at the time)
Dont have the remaining pair with me at the moment, but can access them by the end of the week for a part #/picture.
