What's difference between Icon 56503 / 56505?

I'm looking to replace my rear shocks. I have a 2007 Toyota Tacoma double cab 4 wheel drive.
The one part number is for the FJ Cruiser. I'm wondering if there's something different in the valving or possibly the fully compressed or extended length. it would be cheaper to purchase the ones for the FJ Cruiser. does anybody have any experience with either one of these shocks?

 

Buy the one for your truck and call it a day. They are different part numbers for a reason. I'd assume something to do with the lower mount. The tacoma bolts through on a double shear bracket. The FJ is simply bolted to a single hole in a bracket.

 

I was unaware of the different mounting bracket at the bottom of the FJ. I actually jumped on a cyber monday deal and got the shocks for $136 each + tax
