I have a sneaky suspicion that the 4D0 codes superseded the 443 as the model ranges extended. But it is only a suspicion.

I’ll keep an eye out for a pair while I’m going through the garage, tidying up. I’m sure it’s the same part on the V8.

I seem to recall Colin Aitchison doing some 3D printing of these in Bonnie Scotland a couple of years ago; don't know how far he got with the project......
