I have this unknown Datsun fuse box for sale. idon’t know what car it came from but it is brand new in Original box. came with a big LOT of parts from a Datsun collector. Couldn’t find the part number in any system. According to some inputs N31 means RS30 so it’s most probably from an 260Z or later 280Z. As you can see it is very good shape, with all original fuses, no corrosion on the contacts or anything. If you’re interested, or if you know what car it belongs to. please let me know.
