Yearone Rally’s 17 inch on 69 Valiant- help
Understand, what about machining the taper of the splindle back further so the brake rotor itself moves more negative?
Or the brake rotor hub?
Machining the spindle would move the rotor closer to the spindle, which would cause interference very quickly. The tapers are hardened as well, so that’s not a good option.
The brake rotor hub wouldn’t get you much, and you’d almost definitely need different lug studs with a shorter shank.
I would avoid doing any machine work on either of those spots.
See where this spacer is, is it possible the taper of the ends more positive than another style spindle which doesn’t use the caliper spacer? Looks like another spacer keeps the rotor from moving in further as well from the base of the spindle.

Ok, we have a terminology problem. That’s not a caliper spacer, that’s a bearing spacer. So yes, removing that would move the rotor closer to the spindle. But that spacer is there for a reason. If it’s there to keep the rotor from hitting the spindle, changing spindles probably won’t help, it just means that space is built into the other spindle.
If it’s there because of the distance between the bearing surfaces on the spindle you might benefit from a different spindle. But, the spindles you’re talking about don’t use the same wheel bearings. So, your brake kit may not be compatible with them anyway.
