Banjo is equal lengths side to side.
In Holdens there is generally only 4 x banjo axles ignoring splines and the shorter ones used in UC with HZ rear disc setup (these technically aren’t out of a banjo though will bolt straight into a banjo).
HK-HG. All coarse spline with a roller bearing (like the furthest right in that picture).
LC-LJ. Roller bearing and mostly coarse spline other than those final months of XU1.
HQ-HZ. Tapered needle roller. Coarse early and fine spline late. WB 6cyl drum brake rear (not cab chassis) is the same.
LH-LX. Same as HQ but shorter and 4.25” PCD of course (except L34). UC drum brake rear the same, as mentioned disc brake ones get a bit funky (slightly shorter and have longer wheel studs).
So in that picture, if the fine spline ones with the tapered needle rollers are all the same length then they are most likely HX-WB 6cyl (not cab chassis). Check if the stud pattern is Early Holden (4.25” PCD) or later Holden/Statesman (4.75” PCD). If they are 4.25 they are fine spline LH-UC. I don’t think they are Torana though by that step down from the spline.
If the coarse spline tapered needle roller one is the same length as the fine spline ones it is HQ-HJ, PCD will confirm. If shorter it’ll be coarse spline LH-LX.
The coarse spline roller bearing one can only be HK-HG or LC-LJ. Length will give it up, HK-HG are close to HQ in length.
