Where can I find mega 921 chrome center cap for a 22 inch rim
Simple... You remove the wheel from the car and punch out the center cap from the backside of the wheel.
Remove the center console/cupholder. Remove the interior doghouse. Remove distributor cap.
Screwdriver
The only way to remove it without damaging it is to remove the wheel and tap cap off from the inside.
Remove the center cap, washers and C-clip and the wheel should slide off.
If it is like the Deville models, you should have a special tool that will remove the center bolt. The owners manual will have a picture of this tool. Use the flat edge of the tool to remove the center decoration, and then use the rounded end to remove the center bolt. The hub cap will then basically fall off.
I have a set on 20" Dayton's on my truck, inside the back of the center cap it should say DAYTON.
Car lovers can find center caps for their Chrome Rims even if they are old. You can search websites like Ebay or Craiglist to see if anyone is selling spare parts for center caps or reach out to a dealer and ask for help.
They are made by Exel Wheel Company and not by an auto manufacture.
UNDER THE CENTER/ CUP HOLDER CONSEL. REMOVE CONSEL DISTRIBUTOR CAP SHOULD BE ON TOP.
