I don't know, but I've liked everything I've gotten from them. The key to the axle kit is you can determine width. If you know someone who welds, I'm pretty certain they'd be easy to fabricate. I'm not to proud to steal a design from a publicly available picture. And I've done worse... buy one of the $200 parts, study it, make notes and then return it. When I first starting building furniture, I would hang out in furniture stores with tape measure and note book. That was kind of before the internet.

Good morning Chicky, have a great day
