I've WIKI'd this for posterity (along with more detail) : https://club8090.co.uk/wiki/VW ... headlights" onclick="window.open(this.href);return false; - so look there for whole article.
Although at first glance it doesn't look as if they'll fit at all, the three lugs on back of the new light unit will drop nicely into the three recesses in existing light frame. All you need then is three clips to fix the headlight in permanently. (see WIKI)

Bear in mind they ARE curved rather than flat like stock ones but you don't really notice to be honest.
I have concluded that these units are almost certainly the same as those fitted to the Ambassador car, common on India's streets. Certainly thats where they're made. They are Autopal HL-101 units and they make fancier versions with fluted reflectors but these are bog standard reflectors. For under a tenner, they're a bargain but remember you'll need clips or something similar to hold them in place.
The alternative is to pay £45+ for complete headlight assemblies but for the sake of three clips, they're worth a shot. I think I paid £8.80 for each headlight!
