Sierra wheel studs, drive flange, disc Q??

Does anyone happen to know (even roughly) the thickness of a Sierra rear drive flange (bolt-on shafts) and the thickness of the bell on a Sierra unvented disc? In other words, how much of a wheel stud length is taken up before the wheel mounting face on the disc bell.
Thanks in advance.

Ta. the 14mm bit is what I need but I would want a bit more than 18mm beyond the disk as you have the thickness of the wheel behind the nut seat plus a decent amount of thread in the nut itself.

ETA - Where's Whippy's response gone? Now it looks as if I'm having an imaginary conversation!!

2nd ETA - Ah, back again but below. I'm sure the depth (red bit) of my wheels is thicker than that.

it's about 6mm for the disk and 8mm for the flange. I'd personally want at least 18mm of stud sticking out past the disk as mind the wheel nut can't get right up to the face due to the wheels own tapered seat thickness, especially if its for alloys (the area in red)

I was off trying to get a picture...
