Anyone know where to get hold of the screw in driver side mat fasteners. Over enthusiastic valet service seems to have pulled one of mine out and no doubt in their hoover!

fiat will have them

My stilo doesn't have holes for screw ins it has little black studs set in the carpet. Is this an alternative option as I have standard fiat mats and always wondered how they should work if used properly.

thats what he is missing, the black studs screw into the carpet.

The turnbuckles are not listed as seperate parts on ePER. They appear to be fixed to the the original carpet, not the floor.

Mine must be broken then, I have no turning bit, just a hard black plastic nipple thats fixed to the carpet

I have the turnbuckles as pictured by Davren, but my first Stilo 3 Door Dynamic JTD circa 2003, had the stud type fixing described by Andymacselespeed. The turnbuckles just screw into the base floor matting. Cheers for your input - see what I can google up!
