73 E body front disc brakes conversion on A body. Where did I mess up?

Yea but it happened on my watch. Lot of time spent on this project to understand the do and do not. This was to be the simple assembly of parts but what happens? All the prep that went into this. Not only the front but the entire car was affected. The front end rebuild is the final stage. Been on this since 2018. Yes I know I'm crying in my soup.

Look man, you’ve got a little extra metal on a lower ball joint. You can let it derail your entire project, or you can just grind it off and put the thing back together.

There’s no such thing as a “simple assembly of parts”. The parts are 50+ years old and had a wide range of tolerances to begin with. The replacement parts are made off blue prints or maybe even off a scan of some other old parts and then the dimensions are fed into machines that also have tolerances and the whole thing is put together by someone that’s never seen an old Mopar. Sometimes stuff doesn’t quite fit.

You’ve mocked it up, you can see what’s hitting, knock it down with a grinder until it clears and bolt it together. It would take less time than I’ve spent responding to this thread.
Just a clarification.....
THIS is a steering knuckle:

The factory even clearly defines it.

The red arrows point to the knuckle. The yellow arrow points to the spindle which is part of the knuckle.

The term "dropped spindle" referred to the actual spindle being placed up higher on the knuckle (Closer to the upper ball joint) to effectively lower the vehicle, all else being equal.

No, this is a knuckle

This is a spindle

And this is BOTH

So let’s drop the grammar police routine and not muddy up threads for no reason since we all know what part we’re talking about?
