72 GMC 1500 - upper A-arm shims/spaces, and alignment

[centuryhouse]

Hi guys,

Please excuse my ignorance of suspension issues. My 72 GMC pulls to the right and I noticed the driver's side wheel/tire leans inward at the top. Would that normally produce a pull to the passenger side?

Comparing the driver's side to the passenger side (what I can see of it), it appears there are shims & spacers missing. Am I correct in thinking that more shims & spacers would correct the wheel/tire leaning inward at top? Are they hard to put on? Is LMC a good source?

Pics of driver's side - notice the exposed threading, and lack of shims/spacers:







For comparison on the shims & spacers, here is the passenger side:
