10 spline axles and LS power... Braver man than me haha.
In that case, it depends on which CVs you have. you will have either 32 to 10 spline or 23 to 10 spline CVs. If the former you will need discovery 1 CVs which take a 32 spline axle and have a 24 spline hub end, or if the latter you will need county CVs which are 23 spline at the axle end and 24 spline at the hub end. County CVs are beefier, but weak point in either case will be the 10 spline end of the axle or the cross pin in the diff.
There are a few other combinations that could work but thats the simple version. Basically there were two types of front axle shafts, 10 to 23 and 10 to 32. Also be aware that there were different width hubs and the stub axle has different bushings or bearings to suit different CVs.
Honestly though unless you don't plan on taking it off road id be swapping in whatever good axles are easily available in your area. In Aus its usually GU Patrol axles, but other parts of the world there seems to be plenty of other options. Rover 10 spline stuff is pretty puny, their only saving grace is that its all full floating.
