Take it back - get refund from the shop - order thru a competent Bushwacker dealer - get complete set and install.
I wouldn't let the blame sit entirely on the shop or on Bushwacker, the truth is somewhere in between. I'm too tired these days to deal with poor service, if I couldn't get the parts ordered thru the shop, I'd be calling Bushwacker myself or taking the incomplete kit back.
I ordered through Jeep-Add-Ons - Jeep Accessories, Jeep Wrangler Accessories, Jeep Bumpers, Jeep Winches, Fender Flares - Truckaddons.com
- talk to Chris at ext 1884. Tell him you got his info from the forum here and see if he can help. When I ordered my Bushwackers he gave me a smokin' deal but they were backordered. The few weeks wait was worth it though.
