I am working on turning my 1978 truck into a 1965 truck copy. Part of that is getting the 1978 badges off the sides and putting on copies of the 1965 badges. They don't go in the same place for those years. So we removed the badges, welded up the holes, ground down the welds and covered with body filler. Here is photo. Hopefully we will be painting the whole truck in a few weeks.
