Ordered a new torsion arm along with a bearing and seal kit for my eu37 hub. I was going to jump on it this morning and realized I do not have the 3 O-rings. I have not been able to find the information on the size or part number for the O rings. I live very rural and the thought of blindly driving 45 minutes to the box auto parts store trying to find them concerns me a bit. Anyone point me in the right direction?
