What to look for??

A no fender tag '68 can be a problem to verify unless you have the build sheet. The VIN is nowhere else on the body so it's nice to match the shipping order number on the fender tag to the core support. The VIN should be on the engine and transmission however. The one on the engine is crudely stamped in the rear of the block up on top close the bell housing to the drivers' side of center. The transmission should have a machined pad on the passenger side that has the VIN stamped into it. If those match, I would feel a little more comfortable but there has been some parts swapping on that car. It has deluxe door panels but not a deluxe instrument bezel. The shifter isn't stock. The header panel and trunk lid are missing emblems. The above mentioned engine paint. No wheel opening or rocker mouldings. Repaired fan shroud? Antenna? I'd look this thing over REAL good before I forked any money over.
