is this normal?

Hello everyone,

Just lookng for opinions. I've got a 68 k10 that I'm swapping a dana 60 into. I'm also installing some tuff country 6" lift springs. One thing i noticed was that the castor is different side to side. 7 degrees positive on the passenger,and almost 10 degrees positive on the drivers side. I did notice that the one of the lift spings was slightly shorter when placed side by side. Could this be causing this? The dana 60 is out of a 86' military chevy truck.

Thanks

Shane
