Has the K Series sump plug changed?

[Q Catcher]

I'm replacing the sump on my 2002 K Series (it was damaged by Brittany Ferries ... they've paid for the parts ...) and it looks to me like the old sump plug won't fit the new sump.  It rattles around in the first few threads and then starts going tight way before it should.  I've mic'd the sump plug thread and it comes up at 12.9mm diameter.  Were they half inch?  Is the thread in the new sump 14mm?  What the ..?

Edited: Thread changed in 2003.

Is the hole tapered?

Nope.

I think it has varied over the years. When I asked CC what the thread would be in my 2002 car ... they didn't know. Take new sump to a fastener shop and try metric bolts until you find one that fits .... or car spares shop for sump plugs.

Thanks for your help, chaps.

It's off a Land Rover 300TDi.  14mm.  Part number UAM2957L, complete with copper gasket. Got one from my local 4x4 centre for £3.

Same 19mm across flats, just to fool us.

(Edited to add the correct the Land Rover model and the part number.)

Was the old size 3/4" across flats, and that was the coincidence of 3/4" and 19mm... they're only about 0.05mm different?

A bit off topic but mine was 14mm (2003) and is now 15mm. Be careful when tightening as steel bolts and thin ali are not an ideal match.
