I called and got the shorter ones too. the early kit (or mis kit) was so long that it basically rode on the springs at rest.

I wanted to match the free travel that the original bumpstop has so i shotened about 3/4's of an inch out of it by taking the spacer part off.

photos in no particular order:
------------------------------
shortest spring (long spring cut in half) WITHOUT modified mount:
clicky

short timbrem replacement comparison: clicky

long spring: clicky
ok..I have new modified plate photos at home, but you'll have to wait a couple of hours before I can get to my comp and upload them to photobucket, but it is interesting to see...

OK ON EDIT (more pics)..
hole cut into bumpstop frame pad

shortened mount with full ses short spring: clicky

cut bumper spring on shortened mount: here

I rode around with the short mount with the full rubber spring (the updated shorter one and it was ok, but it got into the stiff rubber spring feel too often. That will be perfect with a 1.5 to two inch lift, so for now I'm running it with the 1/2 length timbren I cut in half. It doesn't offer 100 percent bottom out slam insurance like the other ones do, but I compromised for now until it gets more lift. I think articulation on the rear might be more like this since it rides a bit higher than the original stop.
