Rod,
The adjustable stingers are widely available. Below is one on Amazon that has lots of vertical adjustment. Also, I swapped out the securement bolts for pins and keepers on mine so I could adjust the height without tools.

There are several choices for the interchangeable balls. Here is mine, again on Amazon:

RogerRamRod,
Thanks. I spent 40 years in trucking, it's nice to be able to contribute to the forum as mostly I'm a consumer of info both here and at /6. If you need a rise hitch, get the one listed above and simply flip the stinger over so it points up instead of down. Total adjustment on these things is about 18" when you've fiddled with everything.
