I am selling a new item that I purchased but no longer need for my car. Carmate IF57 rod holder mounting option, with bolts and washers. This is the square hole adapter C type. - Brand: Carmate - Model Name: IF57 - Included items: Bolts, washers, and clinch nuts - Application: Rod holder mounting option Functionally, there should be no issues. However, since the item has been opened once, I am offering it at a slightly lower price than the market. No claims and no returns accepted.
