Someone PLEASE help, FB brake rotor replacement
 

I have an 1984 gs that I need to replace the front brake rotors on and it's a daily so asap. I ordered new rotors and they didn't come with studs in them. The previous owner said he converted the studs to be attached to the rotor rather than the wheel? I don't know if I can simply screw new ones in, which I doubt because there isn't enough clearance, or if I need to order a different set of rotors with studs in them. Any help is greatly appreciated! I keep running into brick walls with this car :/

Ok I did some more research (I'm a beginner at working on cars) and found that the studs should be semi easy to replace but the problem is clearance from the rotor to the hub, I guess u could say, but the longer studs are on the old rotor now with no problems. The new and old rotors are identical and I have no idea how the previous owner got them on.

pictures of front and back of rotors with studs installed please. The previous owner either used wheels studs which press fit in or ones that just thread in.

First time posting pics so hopefully it works. And they may be thread. They aren't flush with the back of the hub. I tried unscrewing them but they are probably torqued in.

Edit*
Just checked the new rotor holes and they are threaded. What would you have to do to make sure they are safe? I've only seen the ones that seat in from the back.

If the they old ones aren't a press-fit, you could try soaking them in liquid wrench and maybe use a little heat and then double nut them then and try to take them out.

Might have to use a impact gun. The top nut would need to be smaller then the bottom nut though.

Do those have an allen (hex) recess in the top?

If you get them out just use some lock tite when putting them back together.

As a last resort if your running factor wheels would be to just buy factory lug bolts.

Yes they do have a hex recess on the top. I think I'm just going to get new studs so I don't have to bother taking them out. The factory ones won't fit the wheels I have. My friend is going to do it at his school since I don't have proper tools to put them in. Thank you very much for the help man.

they're probably lock-tited in.

a lot of heat will break down the lock-tite and they'll screw out

Thanks for the info :) we ended up getting everything changed with only 1 broken stud. Ordered a new set anyways. Now I can brake without going into the other lane lmao. Looks like the next thing on my plate is a lsd rebuild :/
