I am thinking about going a little bit overboard with my lights on my '85. I want to get one of the H4 housings and then use a hole saw to cut out the back and put in e45 HID projectors and ballasts. Anyone see any issues with this besides cost? I think it would be awesome to have new technology HID projectors in my '85 toy pickup. I should be able to adjust them just fine with the stock adjustment. Would the autopal lights be a good candidate for this mod?
