Swivel hub bolts/bolt sizes

Hi, new here.
I’m trying to replace the 3 bolts on the back of the swivel hub on my 197. I’ve contacted Renault and they’ve said that I can’t buy the bolts separate from the part, I have to buy the whole thing. £127
Does anbody know where I can get these bolts from or know the bolt sizes so I can go get them from Webster’s.
I’ve been searching for over a week and have gotten no where. I have the picture from Renault if that helps.
Would really appreciate any help I can get.
Thanks, Gav
It’s part number 1 that the 3 bolts go into

Thanks Turkie, I appreciate that. Will this fit a standard 197 and any ideas where I can get that part number from.
