SBP Centerline center caps

I have a set of old centerline auto drag wheels on my ‘72 Duater. They are for the SBP. The tire shop lost one of my center caps now I can’t find any that fit the small hub bore. The in bore on my wheels is approximately 2.725 inches. All the center caps I’m finding online are for way larger hub bores. Does anyone know where I can get them?

I would really like a set of spinners with the but I can find those either. My help is appreciated.
