I was collecting these parts to build a mini truck rock crawler and I ended up buying one mostly finished.

Trail Gear Rock Defense Front bumper with winch mount. $325
Marlin Crawler rock sliders for 84 to 88 ext cab truck $125
Marlin Crawler dual transfer case adapters $325 21 spline
Marlin Crawler 4.70 gear ratio transfer case low gear 21 spline $375

All parts are new in the box.

 

where are you located? may be interested in the rock sliders

 

Sliders and bumper are sold.
