I bought my 91 3kGT almost 2 years ago and finally got around to taking the dash out to mod a bit and was going to replace the bulbs in the HCU sides because I thought they were burnt out. Come to find out, the actual screw base and bulbs are all missing. I called a Mitsu dealer and they stated that I needed to replace the whole unit because they could not just sell the sockets ??!? Is this true, or does anyone know the part number that I could look up? Or better yet, does anyone have some I could buy
