Thanks Red,
I think if thats the case I might as well get longer studs just to make myself feel a bit better.
I did a search and saw
https://niceproducts.com.au/ thrown in for some studs and someone else mentioned Landcruiser studs?
Not real sure on how much longer I would need. I was thinking maybe an extra 5mm would do.
Stock replacement seems to be
S330 -

It tells me what the long stud is but this is like 73mm in length which is going to be waaaaaaaaaaaaay too long.
I am assuming the shoulder is the section that's between the head on the left and the just before the dip before the thread?
I saw something like this one.
S345 -

Which technically is longer but also has less thread due to the longer shoulder? But if I am thinking right this should give me that extra length that allows the nut to screw further in?
But then one that peaks my interest the most.
S312 -

This one just has less should but I think could be offset by the length?
Any help or advice or even kind words would be great lol.
