Try your darnedest to get a title and register the 54 before you start the build.

Using the 87 vin would not work as the only thing 87 would be the vin.

The S-10 chassis would need a title and vin and then the 54 would be titled as a S-10.

So find a total junk 54 with a title and get it in your name and registered, then start your build with the S-10 chassis and you original 54 body. Now the tricky part the vin tag.

The factory uses a special rivet that you can't duplicate to hold the vin tag on the body. This could pose a problem if an official were to inspect the vin for whatever reason, and this could create a real problem for you.

On the other hand if the vin plate was spot welded by the factory this could be glued to the body with structural adhesive .

Good luck
