hey rob how hard would it be to change the front on the Dodge to make it an Alfa.
Very hard.
So let’s take something I know very well. Volkswagen’s MSB platform, or in Porsche-speak, the 971. This Platform currently spawns the Panamera, and also the Be they Continental and Flying Spur. And a highly modified version of MSB spawns the J1 which is the Taycan and Audi E-Tron GT.
Let’s say you, for whatever wild reason, wanted to make your new Panamera look like a Continental. Using all OE parts? Absolutely not possible. While they share powertrains, suspension, subframes, electrical system architecture, and some other parts, there is a major difference between them. The unibody. Most vehicles these days are unitized frame construction. The only part of it “frame” you typically see is the roof, A/B/C/D pillars, and rear quarter panels. All other body parts like doors, hood, trunk, front fenders, and bumpers bolt on to the frame structure just beneath them.
The position of the frame structure for where these parts bolt up is different between a unibody of one model versus another. So the body parts are not interchangeable.
Different story on something that shares the same positions where fender and bumper supports are. Something like putting and Escalade front end on a Silverado? That’s not terribly hard to do because they essentially share the same frame underneath.
Now if you were a very good fabricator and know how to actually make fenders and so on? You could do what you ask on just about anything. Though the Charger is physically bigger, you could just kind of fabricate your own body parts and expand the proportions a bit from an Alfa Giula and make the swap. The end product would just look like a real life bad photochop.
