Thanks for the additional information
Warranty Number: 7R01T******
Date: 27F June 27, 1967
Issue 1: Where the cowl meets the aprons the fitment looks really bad. It appears the original factory welds are in tact. Is this normal? I know it looks like the cowl panel was replaced with poor workmanship but given the factory spot welds appear to be in tact I have to ask.
Guess your referring to the somewhat large gap between the panels. This was by design and allowed for variables in panel fit while the body was on the jig used to build and align the unibody on the assembly line. The gap is typically filled with sealer applied from the wheel side of the wheel well when they were sealing along the cowl edge
Issue 2: The RH side has square hood hinge nuts and the LH had round hood hinge nuts... is this normal?
Normal (now that we know more about your car) for your cars plant and time period. As they San Jose, transitioned to the new (but no better IMHO) design for the hood hinge mounting points for some reason the stamping plant that supplied them, changed the passenger side to the newer version first.
Would guess your car was actually built after the projected build date listed on your door tag and your VIN starts with 7R01T225xxx to 226xxx
