I am getting ready to re-install the mud buckets on my 62 Nova. The mud buckets use some small nuts that self clip in place. They are like a nut with a spring steel clip incorporated into the nut itself. What are these types of nuts called? Where can I buy them? If I knew what they are called I can probably get them through McMaster Carr. Secondly, does anyone here have a diagram of how the whole mudbucket, headlight mount, lamp adjustment, springs, etc all go together? This is the problem with having may car apart for so long. Old age is not helping either Thanks in advance guys.
