Brad,
Been ordering parts into the thousands of bucks for the last four months from Chevy Duty and the only thing that they have back ordered on me has been the hub caps for my 1950 3/4 ton. VERY prompt (call Monday, ups on Wednesday), several minor mistakes on the pick but they had the correct parts to me the day after I called, no questions asked.
Also I have compared all the major suppliers when ordering and they have the best prices on the majority of their catalog.

The major problem is no single vendor carries every part you’re gonna need. One has this but not that, etc., so your going to end up buying from all of them eventually if your doing a complete restoration.

One thing to keep in mind is a lot of the reproduction parts from all the vendors are not up to the standards of the original part. Not sure but it does appear that they are the ones that are being manufactured off shore. At least the ones that I have had complaints about were labeled Chin! The acceptation is that the parts from India have been as good as the parts from the States.
