If the engine bay paint is original, note lack of LH shock tower decal and also note no dum-dum in the holes in the cowl where the washer nozzles would go if the car had windshield washers. Note black solenoid that appears original... Also note jack-handle style.
Would be interesting to see it up close. Someone that knows these cars could dramatically improve the appearance by removing aftermarket pieces and swapping out correct parts for good used original. Do a full cleanup, top to bottom.
I'm not sure I could live without the 289 emblems though. As interesting as it might be that the car may not have had them, I don't think I'd want to be 'that guy' who has the car without v8 emblems.
