I bought a parts hoard from the owner of local upholstery shop and it included 5 bolt re-drilled fronts and rears. They don't have the hubcentric so I assume they are early.
Do they fit on late spindles?

He also had a set of date stamp 12/69 14 x 5.5 Fuchs. I wanted those too but he wasn't selling.

IIRC the only difference between early and late struts is how the ball joint bolts in.

However the rotors have different offsets and require matching offset calipers.

So no, unless you also swap to early calipers.*

* I might be wrong.

The rotors can be mounted on the spindles but will not align with the calipers. Early struts had a different off set to the mounting ears for the calipers. No mix or match if early and late parts.

Ok thx, I'll have to see if have a set of early calipers in my hoard.

The brakes off my old 72 should be right?

Maybe. they changed mid year 72. and the calipers and rotors only work on the early struts. Ask me or the guy i sold them to how we know.
