Does anyone know what size the O-ring that seals Mile Marker hub caps to the wheel housing? It is the largest O-ring. Went to a local bearing shop with the old one but the closest they had was too thin, it didn't seal anything. Contatacted Mile Marker, they "didn't know" either but they gave a part# 402.03.
I live in Finland and we dont have imperial stuff at every corner store here so knowing the size would help greatly
