Front driveshafts and drop shackles.
 

I have two front driveshafts that fit 99-06 GM 4x4's. One part#15087453 fit's H.D series. One part # 15140566 fit's 1/2 tons. Both were taken from new trucks with less than 500 miles, were replaced with c.v. style shafts because of lift kit's. $80.00 each + freight cost. Also have two new pair Belltech 2" drop shackles part # 6400 fit's 88-06 GM $40.00 + freight cost.
