I have 2 FGp headlight buckets and 1 FGP eyebrow and 1 UK eyebrow.
If you look at my build thread I had to add material to two sides of the eyebrow and all the work to get the UK buckets to work.
The UK eyebrow is too small.
You can see the Bucket with the FGP plastic lens, and the space where the eye brow meets.
I just looked over some pictures and remember how the UK buckets were kinda messed up
