Correct coolant tank mount with pics

Ok, i have an 83 1.9 DG wbx. it has an old/early header tank with metal cap. I am replacing it with the later tank (with Dalek cap) and associated hoses. the only thing getting in the way is having the right mounting 'plate' to fit the 'new' (later style) tank onto. I have just brought a good s/h mounting unti/plate like the one in the attached pic BUT it seems to me that the tank, like the one pictured has a flat vertical plastic piece shaped like a spatular which should sit in something?? and also the top of the tank has two additional plastic flanges with holes which perhaps should also sit on top of mounting holes...?? So is the tank pictured mounted onto a version of the mounting plate which 'fits' and holds it but is not the correct mount? Is there any other mount apart from the very early style....
NB Am selling the original header tank, mounting bracket and pipework. £30- for the lot. When i have fitted this one....

025-121-409D expansion bottle bracket (obsolete – 2nd hand)
No idea what the slat piece you can see on the bottom of the bottle is for. The later mount holds the bottle via 2 screws and the raised flange you can see in the middle of the bracket (below) fits into a slot in the plastic bottle
Looks like this

Cheers Cruz, think this was your pic i got from google. Do you or anyone know if thefe was also an alternative later bottle bracket? I like the idea of future proofing! Thanks

That bracket fits both early mk2 bottle and the later bottle. Though you'd need a damn site more pipes to fit a late bottle.
aftermarket early mk2 bottles are widely available so no need to worry
Basically it goes like this
Early Mk1 (based on the diesel bottle) 068-121-405D
Early Mk2 025-121-403a
Late
025-121-403b

Another thing. In the aftermarket there is only 1 hose and 1 metal pipe that you cannot buy new for the early coolant system and thats the hose that come from the back of the thermostat housing to the head and the long metal pipe that runs across the engine]
