Hawks Motorsports or another salvage yard is your best option. In our country it is illegal to separate a VIN tag from a chassis. A salvage yard might be willing to remove a VIN tag, put it and the matching ownership documentation (title) in the post for you, and crush (destroy) the vehicle. ...but this is unethical AND illegal.
At the very least, you will have to buy a bare chassis, which will save you a lot of weight in shipping, or, buy the section of the car that has the VIN tag riveted to it. It is not uncommon for a car to be sectioned out into quarters or halved for accident repair.
In our country abandoned cars need to have ownership transferred to the "finder". This is a legal process.
There are no "forgotten" cars on our roads. Unregistered and/or lack of insurance is an illegal condition to operate a motor vehicle. Some do drive in this condition, but they get arrested if found, and people like this do not observe the rules of the road so they do get caught soon enough. The vehicle is then impounded until they can attain the proper paperwork, sold at auction, or destroyed.
A private owner who is willing to ship a complete vehicle overseas is going to be a hard find. Listing a car for sale, taking calls / scheduling appointments for viewing, and dealing with payment is more effort than most want to expel. A private owner willing to part out a car and ship just what you need is a one-in-a-million find. My Trans Am needs 3 times more work than it is valued at if that work was performed. I'm still not willing to part with it. Many are in my situation and are OK with it because someday we will repair it, and it's only appreciating in value "as it sits" anyway.
...and that's another thing working against you. Used Car Values. You picked the wrong time to do this. Right now the used car market is very out of line with what we would call actual value. What was a $4,000 car on a good day 2 years ago is now an $8,000 car. Covid supply chain issues has created a shortage of new cars, which in turn has caused the value of used cars to increase dramatically. Every used car has inflated value right now regardless of how crap and undesirable it may be. This is how our Capitalism based society works, it's called supply-and-demand.
It might be easier for you to locate a wrecked chassis in Europe, so contact some European "American" car clubs, there may be an owner with exactly what you need sitting abandoned in a barn out in the countryside.
Your best option in the USA is to look on Craigslist.org for "parts" cars, but, again, the kind of people selling on that website won't want to be bothered with any effort. They want you to show up with cash in hand, and remove the parts or the vehicle at your expense. Also, there is an individual section of craigslist for every county/city in the country, so hundreds if not a thousand sub-sites to look over, and I'm sorry, we're all nice guys and girls over here but that is a bit much to ask for. ...even for someone like me.
Otherwise...
...you buy a complete car at market price and ship it overseas at great time and expense to yourself just like everyone else. Which begs the question to be asked, why bother with the 1994? Just buy a 1996+ and put it on the road. The 1994 should be the parts car, although as pointed out previously, the powertrain between the two years is different. You can transfer them in their entirety, them but you can not easily "mix and match" parts. The interior with the exception of the instrument panel is 100% compatible between years, as is all of the body parts. But there are variances in the electrical, and they have different engines, and computers. If you had a 1996 and you needed 1997+ you'd be in better shape with the v6 vehicles because little changed between them through those years. I'm in the same situation with my 1993 LT1 Firebird. Even though 1993-1997 were all the same, I can not just swap parts over either because 1994 had changes that were improvements, as did 1995-1997. Even though the generation is split 1993-1997 and 1998-2002, in the early years things changed or were refined between years.
Overall though, I honestly do not comprehend your logic. It sounds like you bought the wrong car because you didn't know of or understand your emissions laws. That I understand, but the way you are trying to correct the error is more costly and requires more effort than cutting your losses and buying the right car.
