they should be AEU2522's....thats the actual part no aswel
all early 90s and 110 had them fitted
there 10 spline at the diff end of the shaft, then at the cv end of the shaft there 23 spline, then at the drive flange the cv spline is 24 spline
so in effect its a 23/24 spline cv joint
thats all depending if its the factory axle
get a piccy up of the frive flange, will be able to tell you straight away what cv joint it is dude
