Wheel studs are causing problems!!!

I just got my new set of rims mounted and was all excited to get them on my car and then I figured out that the wheel studs are too short, I can only get about 2 threads in the lug nuts on, so that's far from safe.

It's a 73 dart with front disc brakes. So the front studs were easy, but the rears are causing issues. I took off the studs and measured about .669 thou, and the closest studs I could get are the Moroso .685 knurl and ARP .680 knurl studs. I already had a set of the Moroso studs so I tried to get them in place, I can get them in about half way on the knurl and then nothing. Is there any way I can get them on? Or do I have to try the ARP ones, but that's only 5 thou smaller.

I haven't been able to find a smaller knurl size that's long enough either.
