Westendorf makes a loader for the b7100 and is still available. The problem is that they cost a pretty penny, so I don't blame you for wanting to build your own. For what they cost new, you can find a 7100 with one on it for the same price. You could do that, sell the tractor after removal, and probably get most of your money back. It may cost you less than what it would to build one. Just thought I would throw that out there.
