Here are Dimensions of the mounting points for Kubota L series Buckets. The goal of this list is to help see what newer style Bucket may be compatible with older loaders. The list will be updated as I get more information.  If you would like to participate in helping others and would be willing to send me some measurements of your bucket please use the contact us button. Please refer to the drawing and label your measurements accordingly. Thank you
