have a look on the 'mk1 facelift' thread and get some ideas off that.

there are loads of mk1.5 on ebay, second hand or new unpainted, but TBH, if its white then you could do a pretty good job with rattle cans. waiting around for a specific colour could take ages, especially white and when you do get it its probably not up to standard. there are loads of facelift headlamps out there. ebay or a specialist ford scrappy.
