The Cane Creek Valt progressive springs in a 55mm stroke fit a 185x55mm Trunnion shock so I'm surprised they wouldn't fit a 190x51mm with standard eyelets.
MRP says their progressive springs fit most 200mm shocks and with a 190mm being just 1x cm shorter I would have also guess that their springs would fit.
I'll see if I can get it sorted to confirm and update.
