Need to find a flat piece aluminum plate for a hi-jacker jack plate to install on the Jack plate. Possible aluminum fabricator ? It is 14" 1/4 wide by 14"long inside the jackplate . My 20hp Johnson bracket is only 7" wide it's too small , easiest way to fix this problem if I can find someone who can just make a flat 14" 1/4 wide by 14" aluminum plate. Thanks.
