not try'n to get ghetto on ya,
but conveyor belt works great too, and if you cut it nicely, like with a whole saw it doesnt look bad either. i dont know where port arthur is, but tons of industrial places use conveyor belt, and toss out 100s of feet of belt every now and then, stuff is tuff as hell! and is usually about 1/2 inch--besides it is basicly the same stuff they used to use back in the day, and still do under beds i'v seen now a days too.
answer 2: any 4x4 shop has tons of bushing... cut 'em down to what you need.
