Hi
I have a problem with one of my wheels and am trying to get a replacement but haven't got a clue where to start! I have a 2003 Ford Focus 1796. The alloy has 7 "spokes" to it

Inside the alloy it says the following:
Ford
2s4j_aa
Ronal
1091
7.0Jx
17H2
ET49

Inside the ford cap says:
H9SSX
1137CA
>ppo<
#3714

Can anyone identify them? And point me in the direction of where I can buy one (if that's still possible!)
Deb
