Purchased new inserts for my badly worn headlight and wiper switches from Mid America. With shipping about $18.
Originally was told about EIS parts and with shipping the price was $26 for less than an ounce. Tried contacting them numerous times to negotiate a more reasonable shipping fee like $10 since everyone needs to make money, but they ignored me, hence recommending Mid America. Search term "knob inserts". I'd rather pay full boat to MA than deal with EIS. Such is life EIS.
