Changing to studs on the MK1 and bought longer 13.1 spline ,,,7/16 studs but the ones I took out seem to have bigger splines ?

Splines look tighter / finer as well on the shorter stud - could it be metric thread ?
Just had some useful info
Neil Fletcher Standard Mk2 studs have the same spline as a Mk1 stud and they are the same length - the thread is the main difference in that the 12 mm metric thread is very slightly coarser than the Mk1 7/16 UNF thread but you need to look closely to tell. In actual fact it was so easy to mix them up that Ford put a special mark a bit like a screwdriver slot in the end of a Mk2 stud so people could tell the difference. Those are not normal Mk2 studs.
I'd not be an expert on later 80s stuff but I think that cars like Sierras and such like from that era had a metric stud with a bigger spline. I have heard tell of guys whose Mk2s damaged the normal splines drilling them out slightly and fitting the later metric stud - maybe........just maybe that's what those are but I'dnot be sure!

Short one is off the car and i think it is 12mm thread and 14.3 spline the new long one is 7/16 thread and 13.1 spline ..also just found out the car has MK2 struts fitted which may be the problemOriginally Posted by katana

Just thought if the spline looks finer it may well be 14.3 and not 13.1
