Needing reassurance on purchase

[chevjon396]

In looking over all of the conversation and the details set out in this discussion, I have a question about this car. If the car at issue is the one that has the non factory upper rear stabilizer brackets it can not be a factory Z/28 body. And if it's VIN is "N544693" and this number is also the same stamped at the heater motor hole in the fire wall then this VIN was never assigned to a factory produced Z28. Thus the question is how can that number appear on the block (at any location) and be the "original" block???? Hint: check each side of the rear frame rails in the area where the factory tail pipe hangers mount. Look to see if the frame rail holes for the bracket attachment bolts are threaded on both sides.
