Query: Did what I needed it to

I purchased the Heininger 6000 extension and 6001 threaded hitch lock at the same time. I have not test drove it yet, but it seems to accomplish what I wanted. My bike rack now fits on my Wrangler with room to spare clearing the 12.5in wide spare on the back. I really like having more than one pin location.I was not sure if the lock thread would fit with the extension, but it does. Despite the very little clearance available around my hitch, I did get it to fit and lock. I had to insert it from the left as the hitch wire harness connection interfered with the lock when inserted from the right. I also discovered that the hitch lock on my 2in receiver Yakima rack fits the same threads as well. I may have purchased another one of these instead had I known. It would be nice to just have one key for everything.The only downside I encountered was that 6001 and 6000 were not in stock together, meaning I had to pay for shipping on both from two different Amazon affiliates.
