I have an April of 73 that was very original with 105000 miles on it when we restored it.
I don't think this truck is all original. The overflow bottle on the radiator is added, cause it just drips on the ground otherwise from the factory. The engine hook was black on mine, however, the factory paint on the valve cover, air cleaner, radiator, etc... was gloss black. Yes age and such will dull paint, but that engine does not show signs that it is old dulled paint, it looks like lots of new flat black paint sprayed on it. The front bumper is pretty shiny, but the frame horns behind it and the tow hooks are all flat black too. So are the bolt heads, these I believe should have been gold zinc. The hood hooks should be body colored, the rear footman loops were body colored.
The jack handles seem to be in the wrong place, Mine are on top of the fender under that seat, not on the side, I have never seen them there. The headliner has been replaced, which is a shame, cause the original should have been in good shape still. The factory liner does not have a seam going across it. It had a fused seam running length ways, Spector sells a liner with a sewed seam going sideways, that is what that one looks like to me.
Paint may be original, looks like they waxed the piss out of it, you can see the dull areas on the front grill hinge and the rear door hinges where they couldn't buff very well. Rear floor is pretty fresh looking, as if no one ever touched it with anything. But even if you had a rug, or blanket or something over the rear area, it would still rub the paint off the ribs after 70K miles of vibrations and sliding around, I think. Looks like the rear license plate lamp has been re-painted black and a ground wire added to the rear door hinge, cause the light has a hard time grounding through the hinge and illuminating properly. No factory rear step.
I notice a new shock absorber on it, factory was black or maybe blue colored.
Just can't tell if that is totally legit, but I think it has defintly been refreshed a bit.
