Not sure, I only deal with Series these days. So it is quite possible you are right, and there are two types of balls.I have just had a look and found 2 part numbers, but I’m guessing there should be 3.
The first one is listed as 1983-1993. FRC2644 I think this one is the one the OP needs.
The second is listed as 1994 - 2006 NON ABS.
FRC7065 I’m guessing there should also be a part number for 1994 - 2006 ABS, but I don’t have time to look that one up.
If the swivel balls were the same for the railko bush and bearings, why does Land Rover list 2 part numbers for them?
On the other hand, it could be that the two part numbers are for kits with Teflon coated balls, and the ones with bare steel.
All I have ever done with these is take it all apart, and look at the parts that are actually there, and order what looked like the same.
As far as I can remember, there is a high degree of interchangeability with all the stuff on them.
