Read a number of post regarding the fitting of 14” rims and wheel stud lengths.
After advice on this forum (thanks) I thought I would post some pick of the differences.
The EK ones are shorter and the nut tapers are 45 deg
The EH – WB are about 6 mm (1/4 inch for us old blokes) longer with a 60 deg taper.

Gazza, I'm a bit confused here
You say that wheel nuts up to EK (and I assume, EJ) have 45 degree taper and EH - WB have wheel nuts with 60 degree taper....
This has also been discussed on the FE/FC forum, and someone there said that the 45 degree nuts were used right up to and including HK, with HT - WB using 60 degree nuts.
Had a look at the Holden Master Parts cattledog, and found "Nut, Wheel Hub, FJ - HR, 7407655, 20 of" (note that this cattledog went up to HR only...)
Given that using the wrong taper nuts on a wheel could cause problems, and given that lots of us use steelies FE up to HG on our FE - EKs, it would be real good if we could sort this one out properly...
I'm guessing that using the old 45 degree nuts on wheels designed for 60 degree nuts would be less dangerous than vice-a-versa.
Many of us also use after-market chrome wheel nuts on our steelies too, and it's a fair assumption that these would be the later design 60 degree nuts (I just checked out 3 different sets of chrome nuts in my shed - they were all 60 degree...)
Using these 60 degree nuts on older wheels designed for 45 degree nuts might cause very little contact area between nut and wheel, and could therefore cause some minor probs (like wheels falling off!

)
Can anyone shed some more light on this one?? I for one would definitely like to know precisely at what model the taper on the wheel nut seats changed to 60 degrees, and also whether using the wrong taper nuts can be an issue or not...
cheers, jack
