ece drop spindles - I have issues, what did I do wrong

[brandy hickman]

Installed the passenger side drop spindles today, everything went as planned, no issues at all. I drove it out of the garage to turn it around to start on the other side and i heard grinding noises. Bottom of the spindle practically touch my lip of the wheels (stock 15 inch rims). Shaved off one of the lead wheel weights also - see first pic. I have no clue what I did wrong. Do I need wheel spacers?
I have never heard of drop spindles not fitting a stock chevy wheel.

Some pics from stock spindle as well
