Is there any reason you can't replace all 4 of the bolts with new AN4 bolts that have the same head marking?

with a little Molding....use the head ...make a mold of it .epoxy it on the odd bolt ...passes the eye
better yet ...
Warm the bolt ... push it into wax....for the mold ....remove.
Use "High Temp" silicone....put a tiny bit in the mold .
Put the Blank/oddball bolt into the mold , let set for 24 hrs
You now have a VULCANIZED RUBBER BOND

Folks, Ron is correct. In the car world, originality is King! I know it’s different with planes; you replace everything over time, except for the frame and skin, I assume. It’s interesting that out of over 3700 views, no one could apparently source of of these bolts. There has to a tricycle out there somewhere with one of these dad put on to keep the fender in place!
Thanks to those of you who took time to respond!!
Best, Bob
No need to keep the frame or skins intact on an airplane. As long as the data plate is intact! And I'm sure you're right, you just need to find that tricycle. I think those are just vintage military surplus bolts, but it's unlikely you'll find a cache of them for sale now. I'm sure tens of thousands still exist, but likely all buried in old airplanes or the occasional car bumper or tricycle.
Measure twice, cut once...
scratch head, shrug, shim to fit.
Flying an RV-12. I am building a Fisher Celebrity, slowly.
I found a couple of the same brand of bolts...but they're AN5. I'll keep looking.
[edit]
They came off of a 1946 Cub we're restoring, from the wings.
