Usually the threads on the ends of the bolts are peened after the nuts are installed. Were you able to remove the nuts without ruining the threads ? Then , after reassembly , how did you keep the nuts from coming off?

They weren’t penned. In fact they had no locking nuts and came apart easily. I’m going to put on thread lock later today. There are no brand or other markings on the pedals or the hard slippery plastic blocks. Of course they have metric, #8 bolts. There is no play in the bearings and they spin really well. They cost $18.99 including shipping from America -Eagle - Cycles on eBay.

Seven years ago new replacement rubber pedal blocks were easy to find. I just looked on eBay and they are hard to find, expensive and used. Unless you have blocks this is not an economical project.
I've been contemplating getting a mold 3D-printed and using silicone 'Proto Putty' to create some homemade replacement blocks for awhile now. Even drew up some preliminary plans on Tinkercad. I like the hardware portion of these pedals...but the slippery plastic blocks are crap.

Another option is to hunt down red reflector pedals from Canada. They look much better on a rat than the amber USA models in my opinion.

No reason someone couldn't do that using a vertical mold like @ifitsfreeitsforme uses for his grip manufacturing. There are several grades of semi rigid pvc that would be more than durable enough for blocks. Plus it's typically uv stable so no fading

The original blocks on these pedals were advertised as pvc but ridged as a brick. Anything flexable would be a big improvement. Its pretty bad when your foot shoots forward off the pedal.

There are hundreds of kinds of "pvc" though. Agreed if you could find a polymer that was durable, mildly flexible, and still maintained shape. Many marine grade pvc are like this. Like the flexible stuff they use for dock edging. Tough as nails and built to be outside but still flexes where it needs to

Someone with more know how than I have needs to start making these. I thought there were new ones available about 7 years ago but perhaps they were just old left over parts like mine. Now they appear to be fairly nonexistent, if that’s a possible description. Mine are really nice, made of rubber and never used. I have one more set.

You can also use pedals like these and substitute wood blocks.

For making new rubber blocks, all you need is originals to make a mold from, then mix the proper durometer rubber to get the correct pedal block feel (which might take some experimentation). You can also make them in different colors.

A good place for supplies:
www.smooth-on.com

Also, this guy does a lot of mold making stuff, including figuring out the durometer for reproducing the flexibility of Star Wars action figures, and he's hilarious: https://www.youtube.com/channel/UCzsjHlc0WRwZYwlinsmtM4w

as Captain Awesome pointed out, there are hundreds of grades of PVC. You really have to do your homework before committing to a brand/durometer. You can get "coupons" (sample cards) mailed to you by suppliers if you are a legitimate business.

The next problem after choosing a brand and grade of PVC or any polymer, is finding a supplier that will supply small quantities. They mostly prefer to sell by the palette (hundreds of lbs of raw material).

I tried a pair of those once. Thought they would be cool on a black and red bike. One of them self destructed shortly after install.

But if anyone wants to tackle it let me know. I negotiate about 16,000,000 lbs of resin a year for the company I work for. You only need a slice of that :21:

I don't know that we run it anywhere, but I'll check. Can you pm me a spec sheet?
