Can anyone tell me a "cheap", or at least "reasonably" priced place to pick up a piece of "marine grade" aluminum, (#5356 ?)3/8" thick? I'm looking for a piece 12"x16".<br />I live in a pretty small town and I almost PASSED out when they told me what it would cost...$157!!!! I asked if they understood I was after 12 INCHES by 16 INCHES, not feet!<br /><br />I'm having a plate welded on my transom so I can mount a kicker bracket for my small motor. <br /><br />Thanks in advance!
