Thanks, you've made me do one of those jobs that never seems to get done.
I've had halogen vw/porsche units on the shelf in the garage for 2 years
Just gone from 60W Main /45W Dip to 100 Main / 80 Dip !
The pics should give you the idea on the Porsche type lights.
I've got SSC headlight bowls bonded in (so the tyres rub on them instead at full lock)
The headlight shells are as per your link, & they aren't US/UK handed (they're clear).
The headlight itself is any 7" unit, with sidelight. "Drive on the Left" type for UK roads.
I bought the original setup from Autocavan, now part of German & Swedish. Euro Car Parts should do them too.
The upgrade headlights I got from Europa & their part nos are in the pics.
Cheers
Matt
