I know I ordered them on the Internet. They were stainless, pretty sure I found the size needed from a bolt vendor on Ebay but can’t remember for certain. Wasn’t locally I know that. And I used a hacksaw on the spacers held in a vice to cut to size. Took a while to saw them down but I managed to get em square. A band saw or even a sawzall would have been better as my arm was wore out afterwards.
