I used them during my 67 restoration. I took the bumper, bracket, and rivets to my friends machine shop. The bumper did fit in the press, and the whole job took 5 minutes. Looks factory. It does take a lot of pressure to crush them.

I chiseled off the original rivets and cut threads off an old bolt and had it welded on to the original rivet head and secured with a nut.  That way if I ever want to re-chrome the bumper I can remove the bracket easily.  No one will know unless they reach up inside the bumper.

Totally Stainless in Aspers, Pa. 1-717-677-8811 (totallystainless.com) sells a 5/16-24 x 0.7 flat top carriage bolt.  It's part number 2-0773 and is intended for Ford stepside rear fenders.  I ordered a few, & the dimensions are approx. 11/16 diam across the head, and 3/4 in. from the head to end of threads.  It's in their on line catalog.  Cost me all of .78/ea.

I just went to Lowes/HD and looked through their selection until I found one that looked good, but I did not write down the size, sorry.

I wanted to rivet on the rear bumper bracket as original and bought the reproduction rivets. They did not work for me because the top of the rivet you peen over was too small in diameter, would not fill the hole after peening. I made up my own, plated them dark phosphate, and installed them with an air hammer using a long punch. 
I used the rivets on my '67 bracket, and put a 1/4 in. flat washer on the small section of the rivet, then peened the end with air hammer and flat head attachment.  Worked great.

I have done the same washer trick several times also, this is the only way I know that works well to get them tight.
