Need Help Identifying this Replica

I was contacted by a gentleman from the Netherlands asking for help identifying an Auburn Speedster replica. He says it has no identification tag or plate of any kind. It has a Chevy 350 in it with an automatic transmission. Here are some pictures - hopefully someone here knows what it is and can help him get it back up to snuff! He needs some parts and doesn't know what to pursue or where to get them.














Thanks,
Justin
