problems with cragar SS lug nuts???

it is a 1970 but they woudnt fit on either side, they would just bout fit one thread and wouldnt go on at all after that. Is there any other ones i could use besides the ones i got from summit that were cragar ones. Is there a generic brand i can get from autozone or something that would work or do they have to be the cragar ones?? What do you guys suggest i do? try ordering the right hand ones from cragar?? it just doesnt seem like the diameter is wide enough to get past one or two threads.
