yeah its a common automotive tool to remove those types of retainers. i sell them all day long. <work in a automotive tool warehouse>. They dont cost much but most shops should also have them. just looks like a really messed up pair of needle nose plyers. if you cant find one at the shop... just bring your shift light into any autoparts store and be like hey bitch i need the thing to pull this out... and just get the right size.
