<< A long time ago I bought a set of standard seat swivels and did some

 there to adapt into the vanagon seats. I have made a steel and aluminum
 parts for many of my dirtbikes,trucks,trailers etc. I have alot of practice
 with this stuff so maybe I will give it a try .Ps I am cheap , but I enjoy
 trying crap like this . >>
