Tundra Bilstein 5100s on 4Runner don't fit?

[Slusher]

I bought a full set of 4 tundra bilstein 5100 adj. shocks for my 2000 4Runner after one of my rear stock shocks broke. I took my truck and the shocks into the shop to have them put on and they're saying the lower mounting point on the rear shocks are too small to fit on the mounting point on the 4Runner, and the front ones are too long to fit on the truck. How did you guys get the tundra 5100s on your 4Runners? I've got the stock coils. What do I need to do to make it fit? I've looked around on other threads but haven't really found a decisive answer. Any help is appreciated. Thanks
