I think the center link is the same, but it’s worth checking the part numbers to see if the idler arm is different.
Have you centered the steering box yet? Do this with the pitman arm off. And don’t worry if the wheel isn’t centered, you can r&r it to remedy that.

1.Center the box with the pitman arm off.
2.Check that the steering wheel is level. If it’s not, pull it off and level it.
3.Put the pitman arm back on
4.Now check for parallel on pitman and idler
I’ve been thru this before, it will diagnose what isn’t correct.

Seems like 5 degrees shouldn’t equal the lock to lock difference that you are seeing.
