Is creating your own VIN plate illegal? Technically yes. Is it done anyway? Yes. Can you get in trouble for doing that? Yes, depending on the circumstances. If you're recreating a damaged, legal, data plate it's not as big a deal. Just keep the original in your glove box like I do in case you have to prove all is kosher to a LEO somewhere. If, instead, you're creating a data plate with numbers that are not legally assigned to your vehicle, that's a whole different ball of wax. THAT is where the fraud comes into play that bartamos refers to. THAT is why the 'bolt does not condone and will not allow the sale if titles on this site. Putting a VIN on your vehicle, other than the one it was born with (or legally assigned to it by the relative governmental authority), is fraud. If you do it be willing to pay the price if you get caught.
Now to the OP's question. Assuming you're replacing a damaged or missing original plate with legal numbers, I discovered when I did mine (to replace my damaged original) that Chevy used odd size stamps. I bought 1/4" and 1/8" stamps and they were both too large to be a perfect match to the original. They do serve the purpose though.
My original data plate. Replacement data plate.
