offset bushing
This is very small effect, and not worth withholding caster angle. The benefits gained from adding a few degrees of positive caster will far outweigh the small amount of bumpsteer you might add.
And we're not talking about a ton of caster. The offset bushings will only get you to around +3.5*, as my68barracuda pointed out. Most tubular UCA's will allow for +5*. Remember, the reason the factory didn't add more had nothing to do with bump steer. It was because of the bias ply tires. If you run radials, you want offset bushings, because your radials want more positive caster. Running radials with the stock alignment specs results in a poor handling car and less than great tire wear.
