HELP!!! Lost shock nut & bushing!!!!

I heard a clunk in the rear while cruising today. When I got home I noticed that the rear ride height was low. I tried to add air but no movement. Check air lines, OK....checked driver side shock and 'holy $hitz' it was off the upper body mount. The mounitng nut and 'shock eye bushing' were missing. They are Gabriel Hi-Jacker air shocks. Question is what size is the 'eye bushing' and mounting nut? Anyone know who has them?

Thx, ZooKypr
