Interesting differences. David's measurement of his hitch adapter is markably different from the one on the website that Karl referenced below. Which one is correct for the SA hitch? I bought a standard bolt on tow ball and it is immediately apparent that the holes are too far apart. Here's what I gathered:

3 3/8"  or  85.725mm (from Karl's link)
3 3/4"  or  95.500mm (David's meas.)

1 3/4"  or  44.450mm (from Karl's link)
2 1/4"  or  57.150mm (my calculation)
                57.125mm (David's measure
                58.128mm                 ments)
