Used for a Fairlady Z33. This is a set of two adapters (as shown in the first image) to convert the vehicle's battery terminal B to a D terminal. The left adapter in the image is for the negative terminal cutoff, and the right one is for the positive terminal. I used these when upgrading the battery capacity, but I accidentally bought a B terminal battery, so I'm selling these. The left adapter is just placed in an Astro adapter package. Simple packaging, includes postage via regular mail. Please comment before purchasing to confirm availability.
