i need to find out my 1990 tp sedans wheel stud size so i can buy lock nuts and new wheel nuts. because since putting the factory alloys i haven't changed the wheel nuts, so the alloys are being held on with the factory steel wheel acoron nuts, now thats ok but after a bit of time the more the old nuts are used the more they'll bite into the alloy cos they have sharp edges (designed for steel).
so can anyone tell me the size of the wheel studs cos it's not in my manual and i want to get the right ones first time.

thanks for the reply buffy. went to autobarn and got some nice new smooth and chrome mag nuts and a set of locknuts:D much happyer now.
