Wheel studs

Hopefully someone can point me in the right direction with this.
I managed to snap off a rear wheel stud so need to replace all on that hub.The studs are longer than standard as I am running 7x15 minilites on the back. I can find loads of 7/16 x 55mm length for a Ford knock in fitting. However, they are quoted as a spline diameter of 13.1mm and mine seem to be 12mm. Question is, will the Ford ones fit? If not where can I get the correct size for the Tiger but 55mm length? Also, is there any way I can replace them without pulling the half-shaft ?

Thanks in advance, Andy

Sure i've read somewhere on here about drilling a large hole in the back plate then knocking them out via that. The hole is then sealed with a grommet.
It's on my to do list.

That was me a while ago. Same problem with snapped studs, so went for the upgraded ones. One hole 20mm? in the back plate gave access to remove/fit. Drilled out the hub slightly under stud size. As the studs pull through by tightening wheel nuts, they cut the splines.
Or upgrade to discs!

Thanks to both of you.

Bob, to what size should I increase the diameter of the hole to allow me to fit the 13.1mm dia spline studs ? and would it be better to use a reamer or a drill ? Thanks because this is new territory for me. I have never broken a stud in over 45years of motorsport. Maybe I haven't been trying hard enough !!
BTW great idea to make the hole in the back plate.

I am very jealous of that back axle of yours - fantastic.

Thanks again,

Andy

Long time ago, I think I went 12 mm drill bit. Start small and enlarge is safest way. I eventually found my studs had broken as sleeved wheel nuts were a fraction too long and left a tiny bit of movement in the wheel, although appearing tight. A thin spacer sorted it.
See Dave Herning for rear disc conversion. Connects up straight to existing hand brake.
