To answer the questions:
I am welding them, haven't decided if i am going to tig them, I have access to an alum mig but have never used it before and hear its a little tricky. Its some auto sensing unit...
The material is quarter inch, and the pieces were scrap, hence the limit on size therefore the back and sides couldn't be one piece
I got a cool plan for mounting them, well.. i will be mounting them to a piece of plywood to see if my plan works since my truck is basically still in the early stages... just waiting for the snow to go away
What do you guys think about the rendering with the holes in the back? do it for style or leave them out for "comfort" the bottoms will get pads
Thanks for the comments guys
