Any way to verify a SPID sheet or ID a fake

I am sure there are probably some fakes out there but it there any way to verify a truck and its options? Many options were coded in the VIN but I imagine the re-sellers, flippers or rebuilders could make more money off misrepresenting a truck or just the persons trying to make a clone.

Certain things on my truck line up with what the SPID says but others seem wonky. I do not know enough yet to determine what but I suspect that either

1 -Someone slightly changed the truck and then someone else started putting the truck back to the factory original, but they never finished, and then another person added their flare to it.

2-Someone took my truck and tried to make it something it never was or made it a franken truck. It was repainted and they scribbled the build codes on the firewall

The best I can tell is the only things no factory about my truck are

aftermarket rally wheels added
2nd fuel tank removed
dual exhaust added
door protection molding removed
aftermarket air cleaner
highlander seat was replaced with a solid-color bench
repainted like a factory paint job
charcoal canister removed

I really don't care as it is a nice truck and I will enjoy it but it would be nice if there were factory records to verify it. I am sure an expert could point out a lot more things too. I am torn between trying to return it to factory's original. The thing is I like some of the mods and would probably never be able to get it original enough to pass muster at a car show for looking original.

I wont fret about it but I would love to know the true history of it and where it has been and what it has seen.

Your SPID looks authentic to me.
It was common to have chalk markings on the firewall.
Rally wheels came out after 72.
Dual exhaust may be factory with a big block.

That is a nice truck, you should just go out and enjoy it.

Yes, big blocks got dual exhaust. As for the vapor canister, it might behoove you to reinstall that. Either gas cap is going to put some sort of pressure on the system, unless the vapor line is securely closed off. That may already be the case, if you aren't smelling fumes.

I am only getting a slight smell when I fill it to the fill tube. I also have a new gas cap on the way as the inside gasket on the current one is all dried up.
