Aside from listing all of these parts on one page, this is an important ingredient for proper presentation of a show car. Unless otherwise specified, "CLIP" is a P-clip, "CLAMP" is a hose clamp, and all parts are zinc plated steel. I hope to post pictures of many of these parts. The original P-clips have rolled up edges to avoid scratching pipes or abrading the wiring cables.

Addendum 3/31/16:
BMC part numbers for the common form P-clips will look like this:
    PCR0411
PCR = P-Clip with Rolled edges
04 = tube diameter in 16ths of an inch -- (1/4-in dia pipe or cable)
11 = bolt hole diameter in 32nds of an inch -- (11/32-in hole for 5/16-in bolt)

BMC Standard C1 Cable and Pipe Clips (2.0-MB PDF file) Full P-Clips
BMC Standard C2 Cable and Pipe Clips (1.7-MB PDF file) Half P-Clips

Moss Motors has a web page listing P-Clips by dimensions if you need to buy a particular size.
