upper control arm hitting spindle

[Tukn22z]

well im installing a mcgaudys disc brake kit with 2 1/2 drop spindles on a 1970 c10. The problem i am having is my upper control arm is hitting the top of the drop spindle. I've read people saying trim the upper control arm a little so it doesnt interfere but i feel like the upper ball joint isnt seating correctly in the spindle. Now i measured the widest part of the taper on the ball joint and it was around .708". I measured the widest part of the taper on the spindle and it was around .735". does this sound correct?

The ball joints im using are MOOG Part # K6024

These are the spindles :

Do you have any weight on the suspension yet?

i had the jack under the lower arm from when i installed the coil spring

When you drop the full weight of the truck down, the suspension should cycle down enough to open up the gap between spindle and control arm.

I have the same spindles and I just didn't like when I jacked up the front I couldn't turn the wheels... so I fixed it by trimming the upper control a tad bit and smoothing out the top of the spindle.

Now that I have a lift in the garage, I'm happy I did this. My truck is on the lift a lot and it would be a pain if the front spindles were hitting

check it out in my photo build thread.

got the same problem with my 70' - just installed my disc brake kit (McGuaghy's also) and took it down to have front end aligned- mechanic says it calls for .5 degrees camber but the best he can do is 1.9 degrees both sides- have you encountered the same issue?
