Bristol 403 and Lucas PL 770 headlamps

[Rocket Roller]

Dear all,

As probaly some of you may know, I just bought a Bristol 403 rhd in the UK.

Once I live in Portugal, I'll have to change the headlamps onto right dip
ones, and I was cosidering to get a pair of those glorious Lucas PL770, with
flat glass. The car has others, the smaller ones.

I've been heard that those bigger PL770 simply don't fit later Bristols 403.
By the other hand I also heard they should fit if you change the buckets, or
inner shells.

Any clues?

Yours for longer engine roars,
