1982 S3 Master cylinder parts.

[Nigel Riches]

Well, that didn't go very well, so, on with the original question, 

I have a Lockheed M/C the casting number is 70 3211 426, and the ali tag attached has the numbers 4222 404 19 impressed on it, this appears to relate to installation on Vauxhall Victors, Ventora, and Viva, but I can't find much info or diagrams of this item.

The component I need to replace is the pressure differential warning contact, a small plastic item fitted to the underside of the unit, I have some how got a number from somewhere, L4177-713, this is written on one of my many pieces of paper, as the number for this thing, but so far trawling tinternet has drawn a blank.

I could probably just buy a plug and close the port off, but Mr. Inspector has to do some further tests to allow me to put the car on the road, and if the car has a switch / light / system it should work, and I would like to keep it as close to original as possible, mad, yes I know.

So the great hunt for the unobtainium contact is on.

Any pointers or info gratefully received.

Nigel.
