I have a 87 Sidekick and want to get some 5 spoke Samurai wheels for it. What year Samurai wheels will fit my Sidekick? 

The lug patterns are the same. I believe that the samurai wheels have less backspacing (wheels would sit in closer to center of vehicle and may cause some rubbing (not sure though)

Samurai wheels have the same bolt pattern as most trackicks (trackick bolt pattern changed around 2002, I think).
Samurai wheels have less backspacing, so they would actually set farther away from the frame (wider track width).

Pretty sure you don't have an 87 sidekick either...since they weren't made until the 89 model year.

Duhhh, thanks for the correction Skyhiranger. My mind was out there this morning...
