Hello Doug, thanks for reaching out, and for providing those pictures. I have bad news and good news. The bad news is we do not offer a center cap plug that will fit your caps. The good news is the AC-490 TT center cap is a standard size, for a 4.9" pilot hole, and we do have a suitable replacement for the center cap. For that, I recommend the following:
- Lionshead Trailer Wheel Center Cap w/ Snap-In Plug - 4.88" to 4.9" Pilot - Stainless # LHCS109-SI60C
