And here's another way of looking at it. What parts of the vehicle can now be bought after-market/new? I'd say it's almost possible to build a "new" Scrambler, since you can get the body pieces, frame, etc. Axles and engine can come from anywhere. For example, Frame:
https://www.quadratec.com/products/...Z9NzhtP8vf-D2CV6oX1-8nzi0yJnhflBoCvGcQAvD_BwE
You can build something that might drive, but if you want original style top, doors, bulkhead, rollbar... anything Scrambler specific, they don't make it aftermarket anymore... some companies did, and now they don't, then you hear rumors that they "might be"... but essentially the market is just not there.
If there are only say 10,000-12,000 Scrambler running/driving around, then there are only 10,000 potential sales for those parts in the aftermarket and from a business perspective you never get 100% of the sales... you might get 10-15% of that market.
Compare that to the sales of brand new JKU or Gladiators and the want to be different and custom on your brand new ride... you know exactly where they are going to spend their time and money.
The frame company(singular) is the only one left from 3-4 through the 90's and into the 2000's.
They also make frames for any Jeep and do custom work, but a lot of that is made to order.
Quadratec might "sell" them, but they are a front end, the order goes to the builder and they build/ship it from their warehouse.
But to
@ag4ever point... only a VIN will make it a Scrambler... you build something custom with all sorts of parts, you can't register it without that VIN... usually both of them (windshield/body) and in a lot of states a clean title. This is where there is a lot of problems that lead people to wanting to buy rusted out hulks just for the VIN/title... which then makes 1 less that you can count towards the total.
