50 and 52 pitch. These are outlet parts purchased for maintenance. I'm selling them because I have extras. ※The image is a sample. Although they are unused, please do not purchase if you are looking for perfection, as there may be scratches, dullness, rust, chips, paint lifting, color unevenness, peeling, etc. due to transportation and storage as outlet items. We remove defective products and those that are too noticeable according to our standards during inspection as much as possible, but please understand.
