This is what I found on the ten list forums,
Late Offset Cars (87-88 944) can backdate to early offset parts and early offset cars can update to late offset parts. In these cases the spindles, hubs and steering tie-rods must be changed along with the control arms can caster blocks. Also the wheels need to be changed to ensure the right offset.
If this is the case, I think I have all the parts I need, except for some early offset 15x7 phonies.
I have a beautiful brand new set of early LCAs, and I would hate to see them go to waste.
