pre and post galvanizing advice

Sorry - Should've clarified that. Mine are UNF. It's a 1976. I guess the metric change point was around 1980?

Sorry I should have said this a 1983 series 3
It is 8 mm

Did they change every thread on the vehicle at that point, or are post-1980 models a typical hotchpotch of imperial and metric fixings?

I'm thinking it'd be a fair job to change the tooling for every thread.

There is a mixture , i havent found them all yet,

^^ That one! typical british car industry, swapped over but kept using the old fixings until the box was empty.

That is like my old 1971 Vauxhall Victor Super 1600. It had drums all round but earlier fd's had discs on the front. I had an alternator but my mate had a dynamo same year/model. There was something else but I cant remember. they get to the end of the model and bung on all the spare bits that fit.
That was a rust bucket.

The wheel studs on my 1972 (First year) Series 3 are metric (M16 x 1.5 thread). The nuts are 27mm A/F.

Even my 1990 90 has some imperial fittings.

Took the bulkhead and a few other bits in the back of my old Astra for a trip to Wedge in Eastleigh for galvanizing.
