Parts - light switch, door lock barrel
 

Looking for some pointers for replacement parts for my 411 S4 which are not on the cross-reference list:

Headlight rocker switch - the casing of the original is broken and various repairs are not holding up. I sourced an MGB switch which looked the same from it's picture but turned out to be narrower. Is there a direct replacement available?

Door lock barrels - the locks are very worn, esp on the drivers door, any narrow metal implement will unlock it. Are replacement barrels available?

Any hints appreciated

Toal guess but maybe the switch used in the contemporaryJaguars and Rolls.?

You have two choices for the light switch

1/ Holden parts Lucas 39823 three position switch will work and fits the dashboard but does not have the correct markings . about 57 pounds .

2/ Graeme at Bristol spares has the correct switch with the correct markings about 70 pounds . Usually the first choice for anything Bristol

NB the light switces on 411 have always been a problem make sure you have relays installed for your high and low headlights my 411 mk 2 didnt have them and the switch would get quite hot and eventually fail.

If Bristol car Parts cannot help then it is worth trying BODA , I found new door handles and various other parts for V8's even though they specialise in 6 cylinder spares.

I need to check, but I had a few headlight switches made a couple of years ago, one of which I passed on to Graeme at CBCPC. I will see if I have some more....

Graeme at Bristol spares was able to supply a replacement lock set, now fitted. No stock currently of the headlight switch with the correct fittings, but for now I have adapted the MGB switch, which is working fine. Also fitted replacement radiator cooling fans (VW aftermarket units) and new alternator, and a new Edelbrock AVS2 650cfm carb, which should be more efficient than the oversized Performer 750cfm, so good to go..
Thank you for the suggestions.

Dezelsky, do you have part numbers and/or the vehicles the VW fans were fitted to please?
If it helps anyone, on my 411 S3 I'm currently running 2 x 12" Citroen BX single pusher fans, as pushers in their original shrouds. It's working fairly well here in the UK, both at idle and at speed.
Better than the originals, certainly, which on my car are 10" Kenlowes and I think may have used heater blower motors. They're in a shroud which appears to cover more of the rad matrix that would be ideal. The BX ones leave the great majority of the matrix clear.

Hello Mr Green, I fitted 2 aftermarket VW fans sourced via autodoc.com, part no:7022488 https://www.autodoc.co.uk/nrf/7022488. You are right, the fan blades have a much bigger surface area than the originals, so tend to restrict air flow a little, but I assume they just keep spinning with the force of air before the automatic thermostat switches them on. Currently on another long European trip and so far so good, they are doing their job well.
