I just purchased a mid 80's NH-L455 and I'm not sure what type of attachment is made to the bucket. I am familiar w/the universal quick attach, but not sure what this type is called. I would like to convert my skid steer to the universal QA but the converter kits I've seen are over $500.00. Is there a cheaper way to covert it? or if not can I find a weld on plate for my fork so I can convert my fork to this NH-attachment type? I hope this makes sense. Thanks, George
