Any prior owner could have taken the turtle top off any van, and installed it on their GM van.

You should be able to take off the old parts, and take them in to get the correct parts. Your dashboard VIN number (under the windshield) is the correct number to use on your van.

You would be confusing things if you give them the RV manufacture information.

That doesn't appear to be a GM vin number. Look for a plate on dash or in driver's door area. Surprised Ford built it on GM chassis.
Here is link for ball joints. I would suggest getting the upper control arm assembly with the ball joint installed as the control arm bushings go bad.
