Well bit of a luck, I had found a 12.7mm drill and drilled the stud holes, I think they was just rusty as hardly any swarf came off so they are now ready for the fiesta/focus studs at a later date.
Moving to the car itself, I had been redesigning the indicators, mainly the way the lamp is situated in the back, that's all done and works a treat. I had a slight over sizing of the rubber seal , or now it's TPU. I did make them with a cut at the bottom so it's easier to fit on the indicators, some super glue to joint them.
Using MarkA's favorite nutserts again to hold the housing on the body and I just run a thread in the housing for the lens, all bolts are ss and m4 cap screws
Even though the housing is orange, I did apply alfoil to help the reflecting appearance

From inside the arch you can see the nutserts , I used alloy ones as I thought steel ones will start to rust being in a weather area

This one looks a little off straight but it was later fixed

Using a jump pack to power up the LED bulbs

This has a orange led bulb so I'm thinking to go with clear lenses, any objections??
