Altered Vin. How to figure the original VIn

your only going to get a partial vin and most likely only partial sequence numbers at best. there is not a vin on the block or trans either. if you can't find a previous owner with any paperwork, I would say just leave it alone. if it bothers you that much , remove the tag and build a drag car. playing devils advocate, you seem to be the only one that knows., , well... not now lol
