90% of the time the 8 9 and 10inch wheels are hk holden stud patten witch is the same as torrana. Are your wheel nuts 3/4 or 13/16?

Just did a bit of trig and i think this should work

Measure the distance between the centres of 2 side by side studs (not opposites)
Divide this distance by 0.58779 and that will give you the PCD (pitch circle diameter)

hq no but ht is same as hk.. I work with boats and trailers all day and deal with this very problem with customers. Some trailers have ford stub axles and holden hubs fitted and vise versa. Easyist way i have found to tell an early holden be it ht torrana hk hg eh ej etc is that the studs are 7/16 unc and take 3/4 nuts where as ford have 1/2inch unc studs. Most light duty trailers such as tinny and Jet ski trailers usually use holden ht stud patten or as refered to in the industry Light duty, Where larger trailers usually use for stye for the added strenght.
