1969 F or X Body conversion to LS Brakes

[Ranaexcavating]

I have a 69 Nova SS with the OEM front disc rear drum set up. Just picked up a complete LS front and rear disc set up and want to know if the 1969 disc brake spindle and one piece OEM rotor/hub can be used if it is machined to be used as a hub. By that I mean the rotor part of it is fully machined off to allow you to bolt the standard LS rotor.

I have searched and only found reference to using the drum brake spindle and hub when converting to the LS Is there any difference in offset that I should be aware of?

Thanks Joe
