I am wanting to purchase a couple of impliment for my B7100. I know it is cat 1. I purchased a pond scoop ( used ) I may need to do some fabricating on it to make it work. But for 50 dollars cant complain.In the future what dimensions do I need to watch for on distance between pins on the lower links and length the top link hooks to? Hope you understand what Iam asking. This time I will be doing like dusty if it dont work use welder, big hammer,grinder and saw.Thanks in advance . handyman:
