I may have a solution for you, but I don't see a lot of information about the part numbers that you provided; when I researched this the only thing I found says that the A52478-1 is a standard 2" kingpin that was used on military trailers. If this is the case then the Buyers Products # 337KP20031 will work for you.

We do not have a 3-1/2" kingpin available, which would be the next largest size.
