Just to followup on this in case anyone is following....
Did 4500 miles on the Bilsteins, with the longer 24-014014 up front. Nothing shot through the floorboards, so it must be fine. And it rode great. The original front shocks were completely dead. No noticeable difference on washboards and lips in the road, but killed most of the wallowing around. (I also read proper tire pressure goes a long way to help there.)
On the rears I couldn't get both washers on up top, so I only put one on the bolt side. The bushing is just too fat and the dropped floor gets in the way. I figure over time as the bushing compresses I may be able to go back in and add the second washer.
