S711 M Seats a universal fit?

[Swen6]

Evening all,

As per the title really, are the M seats identical across the G Series range? Perhaps baring the seat frame.

They come up every now and then on eBay but might not always be for the G01 X3 we have, so if the opportunity of a set of 340s or similar became available would they fit the G01.

Thanks for any useful info 👍🏼
