mused:

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Lurch
saying something like:

Is the same cistern used for both the low level toilet and close coupled
toilet (the latter being fixed with a clamp plate underneath), because if it
is, I will only need to replace the toilet pan.

Hope that better explains things.

Yep, bit clearer now. You need a new pan and cistern!

Not necessarily a new cistern, unless it simply doesn't match the new
pan.

Suppose you could seal up the fixing holes and use a close coupled
cistern, but you might also need to change the syphon. FWIW I'd just
change the lot, but you may not need to depending on how bodgey you
are.
