Clutch plates

Reassembling my '47 G80 primary drive after fitting the Alton Alternator, I compared a new plain clutch plate supplied from AOMC Parts, and niticed it was a lot thinner. 2mm thick instead of 3.5mm thick. Thats a difference of some 7.5mm total thickness of plain plates in the clutch.
I must admit that I've not seen 1/8th plain plates on a clutch befor, maybe 2mm is thick enough, but what difference will it make to spring adjustment?

the clutch usually has one thick plate 6-x-2 and 4 thin plates 5-x.
measured the thin plates on my spares clutches and tehy are circ 1.2mm thick , thick plate circ 3.5mm thick

Aha! previous owner obviously thought thicker must be better!
(He seemed to think the clutch center tab washer wasn't necessary either)
Thanks for the quick & helpful reply.

Did you mean the steel plates or friction plates ?
friction plates are circ 4mm thick
500 has one more plate than 350

As I said, plain plates.
