are you using a stock style Chevy steering or crossover steering? If you are using stock style have you installed a raised steering arm? If you are using crossover is there a reason you need the spacer? Draglink interference with the spring? We need some more info.
If you are using stock style steering then you and get a raised steering arm to help conpensate for a lift. If that isn't enough you can get a drop draglink to help compensate for larger lifts.
If you are using crossover steering then as mentioned above Sky Manufacturing sells 1" steering arm spacers and the 1" extended steering arm stud kit you will need to run a spacer with crossover steering.
