SSBC replacement parts

Thanks, without caliber 67 mustang, the other is the SSBC, the rotor sure looks the same, not sure on the lug spacing. View attachment 1715447434 View attachment 1715447435
Hi
what's the name of the part that holds the brake pads in place? (a piece of it visible at 11 hours on the picture) Looks like I've lost it... I should have 4 of them for my front...
