Black rivets are the OEM fastener.
I use stainless screws up top and at the bottom I put a 3/8 inch rubber spacer between the cover and the longitudinal to allow debris to fall out instead of getting packed in there.
Partly true....
Black rivets came in with the black plastic sill plates in 74 MY & were 74-76, before then they were white plastic rivets on the aluminum sill plates/rocker tops.
(11/912/930 of the era also used them & the later version went to clear-ich plastic rivets, which Porsche & other suppliers still sell.
The bottom used the "cheesehead" slotted screws, & IIRC it's in the size Curt mentioned.
PS - I forgot the black rubber spacer & other washers, but rgalla has them pictured above (cheeshead screw is the one on top right btw).
You can find the size & type of most fasteners in the 914 parts manuals, & if you don't have one you can download a pdf one from the Porsche website, under Classic section's Documents (for the latest version), & at Jeff Bowlsby's tech & factory docs sections for a bit earlier ones.
http://bowlsby.net/914/Classic/Great references to have on hand for these types of things!
Once you have the OE fitment item(s), then you can decide on the mods like those suggested above, or stick as close to original if you're into originality corectness.
