Zero as in ZERO QC control/accountability. Not surprised.
I tried gathering a list for 67 and 69 cuda. I started out with only a 3-4pieces, short list but "must haves" coming from 2 warehouses. Added about 6-8 more parts totaling $200(before shipping). Now the bastards are shipping from 7 warehouses and shipping is $100. No way whatsoever to consolidate them. I just trimmed my list down so shipping was bearable. 3 pieces coming from 2 warehouses.
I feel your pain.
