I need to fabricate some spacers for my shiftkit's U-bolt exhaust brackets. Basically a 1/4" thick piece of metal 2 1/4" long, 3/4" wide. I'll need three of them. I can probably have the lengths cut myself, but I won't be able to cut the width. So, a bar of 1'4" thick by 3/4" wide by whatever length is available. Is there a place where I can find a variety of stock metal in small sizes like this?
