I have acquired a '66 Longbed 4x4, and I know there are some electrical issues that will need to be sorted through. Does anyone know who provides new wiring harnesses? Thanks for any help!
John [email protected]If you are interested in my '66, make me an offer! I also like doing work, and if you need some done, let me know! Tecnically I live in Southern California, but not for much longer, going back to the MidWest!
