There are more listed in the shop that are Lucas. To see them put in the keywords ESCUTCHEON PLATE TRAFFICATOR LUCAS 

There are TWO singles here to choose from here. EACH is the price shown. You CHOOSE. I have put them here next to each other so you can see the three together. The third one has sold.

They are all singles and will work for square arm 7 1/4 inch trafficators.... 

Be aware Lucas is a long raindrop shape, and whilst these will work for Lucas, it is not shaped like a raindrop as the Lucas one is.

The fancy one (now in the left-position) is a Trico one. It can be used for Lucas, but the shape is rectangular... the Trico blade shape. 

The other is a plain one, slightly smaller in length... not sure what for... possibly VW.

Sorry, both are singles.

lengths 

Trico hole centres 250mm, inner slot 205mm. width slot 14mm.

These two are for 7 1/4" traffs. 7 1/4 is defined by Lucas as the distance from the axle of rotation to the tip of the blade.

The third one is 224mm hole centres, length slot 195mm. Width slot is 13.5mm.

To look for items in my shop, the easiest way is to save any one of MY 2400 items in your watchlist... Then,  whenever you want to peruse my 2400 items... simply click on the hyperlink called “visit store” at the top right of this item.  That will take you to a page with my 40 store categories... click the category,  and that category will be displayed with photos on the right... thus a “window-shop”.

Plodding through the Ebay mire of the general search box... or the “see other items” hyperlink  is simply the way to insanity.

If you’re using Ebay’s useless mobile app, I’m sorry... I have no idea how you will find them… this app is a real shocker/compromise in quality and half the stuff is missing. Go to your PC is my advice.
