Fiat 80/90 seat

[80-90]

Looking for some recommendations on replacement seat for an 80 90. Had a grammer ds85 in it I think.
Most of the replacements out there now seen a lot narrower on the base fitting. Will they all need a bit of tweaking to get them to fit or anyone know of one that might go straight in ?
One place is telling me that the KAB XH2 U4 that goes in a 390 would work.

You are best getting as good a seat as will fit in there even if does mean drilling a few holes
The 300 series seats weren’t overly comfortable iirc
