Access to spare tire winch

So today, amid the nasty wind and rain here in the West Puget Sound of Washington, I got my first flat tire that I had to change on this pickup. The two others that I had I was able to get to Les Scwab before it went flat. So my problem is, how the *$%#& do you get the wrench onto the winch without issues? I spent a half hour on the the side of the road trying to get it in the right spot. Somewhere on here I saw a post a few years back where someone used a plastic pipe fastened under the bed that guided the wrench to the right spot. I used the search function with several queries and no luck. Any help?

 

Thanks, DoorDing! That's the exact post I was looking for! Thanks also to whln for coming up with that idea. Hope that will fix my frustration. Thanks for TW members!
