I just finished installing headlights from a '96 van on my '91 Previa, cut off the HB1 socket and crimped in a new HB2 socket. I put Philips X-Treme Vision 9003 bulbs in there and used the 3M headlight restoration kit to clear up the foggy lenses and it made a big difference. I need to aim/adjust the beam but am missing all of the 8mm plastic ends that go on the stems. Can't get any of them to budge; I tried several pairs of pliers but they slip and end up mangling the threads on the stem ends. Any ideas on other tools/methods to use?
