Depending on the amount of lift (OP doesn't say, but implies a lift when he said, 'spacers'), longer UCAs may be required to achieve a good alignment. IIRC, up to 2" can sometimes be OK without it (YMMV), but from other threads here, 3" will need it.
Speaking of alignment after a shock swap: I was surprised at how far out my alignment was after simply replacing shocks on my stock ride height FJ. It drove OK, but the shop (which I trust) showed me the before and after measurements.
Unfortunately, as 71gs3504sp pointed out, in my case, my adjusting bolts were seized and required cutting out. So, I still have my stock UCAs, but now have a brand new pair of LCAs (and heavily anti-seize coated) alignment bolts/cams, as a result of my "simple shock swap".
Back to Dirtdog: did you have any trouble with the alignment after fitting your new dampers?
