It came about as I recall sometime in the late 60s when I was working for t=

ers instead of zinc, or t=E2=80=99other way about on all cars for Sweden. T=
hat allegedly precipitated the Belgian assembly plant seeking to use metric=
 fasteners in certain areas, though not all, in their build sequencing. Cov=
entry still built quite a lot of components that went into the kits for Bel=
gium and for a while, most if not all cars going to Sweden were built in Be=
lgium. Later on, Sweden destined cars reverted to UK build and I think it a=

 the cadmium and zinc issue which remained in place. However, it wasn=E2=80=
=99t plain sailing all the way in the Coventry and London service departmen=
ts because the fitters started moaning about not having appropriate sized s=
ockets and spanner=E2=80=99s for oddball UK home market cars that found the=
ir way in with strange metric hardware. All in all, one humongous cock-up a=

 in the first place. Probably some acne ridden long-haired lout just out of=

<p class=3D"ydpe91e013cyiv0239132177MsoNormal">It came about as I recall so=
metime in the late 60s when I was working for the company in London. What s=
tarted it (IIRC) was when there was an engineering change bulletin brought =
about by Sweden requiring cadmium plated fasteners instead
 of zinc, or t=E2=80=99other way about on all cars for Sweden. That alleged=
ly precipitated the Belgian assembly plant seeking to use metric fasteners =
in certain areas, though not all, in their build sequencing. Coventry still=
 built quite a lot of components that went
 into the kits for Belgium and for a while, most if not all cars going to S=
weden were built in Belgium. Later on, Sweden destined cars reverted to UK =
build and I think it all died a very quick death and we reverted to imperia=
l standard, apart from the cadmium
 and zinc issue which remained in place. However, it wasn=E2=80=99t plain s=
ailing all the way in the Coventry and London service departments because t=
he fitters started moaning about not having appropriate sized sockets and s=
panner=E2=80=99s for oddball UK home market cars
 that found their way in with strange metric hardware. All in all, one humo=
ngous cock-up all round and I don=E2=80=99t think anyone was sure who had s=
uggested it all in the first place. Probably some acne ridden long-haired l=
out just out of university with a Divinity
 degree and who wanted to make his mark and change the world. Quite likely =
the same person was later moved into Purchasing and decided to change the m=
etallurgical spec for Stag cylinder heads - and that=E2=80=99s somewhere no=
-one needs to go, EVER!</p>=20
