Spare wheel lugs for SL280

[nandasl]

Hoping someone can advise - after a puncture I found I did not have wheel lugs for my spare steel wheel, as they need to be longer than those for the AMG alloys fitted to the car. Local Mercedes dealer no use at all, said only available with new car and cannot recommended substitutes as damage may be caused if using the wrong ones. Does anyone have a SL280 year 2000 with steel spare and can say what lug length they have? Attached picture of wheel. Many, many thanks!

Best way is to try the standard one through the alloy and see how much it protrudes then try any new one through the steel spare and see how much it protrudes? Maybe my memory is playing tricks but I remember steel spare wheel lug bolts being shorter than their alloy equivalent ???

Thanks Graeme - it seems mine are the other way round with alloy shorter than steel, but I might have to do similar to your suggestion with a tape measure...
