* Transmission Differences: A 4WD transmission is significantly different from a 2WD transmission. The 4WD unit has an additional output shaft for the transfer case, which splits power to the front and rear axles. Your 2WD vehicle lacks this entirely.
* Transfer Case: You'd need a transfer case to distribute power to the front axle. This is a large, complex component that requires its own mounting points, driveshafts, and control system. Your 2WD chassis is not designed to accommodate this.
* Driveshafts: You'll need front driveshafts, which are absent in a 2WD vehicle. You'd have to fabricate or find compatible driveshafts, and you'll need appropriate differentials.
* Differential: The front differential is another major component missing from a 2WD vehicle. This is a significant addition that requires mounting and integration with the chassis.
* Axles and Suspension: The front suspension of a 2WD vehicle is generally lighter and less robust than that of a 4WD vehicle. You'd likely need to upgrade or replace components to handle the added stress of four-wheel drive. In the case of a Camaro, the whole front subframe might need modification.
* Computer System and Wiring: The vehicle's computer system needs to be reprogrammed to control the 4WD system. This often requires specialized tools and knowledge. In modern cars, this is extremely complex.
* Fuel System & Exhaust: Modifications to the exhaust and possibly the fuel system may be required to accommodate the added components.
* Body Modifications: In most cases, modifications to the vehicle's body might be necessary to accommodate the new components, even if you somehow manage to fit the transmission itself.
In short: This project is a complete frame-off restoration-level undertaking. It would be far easier, cheaper, and safer to simply purchase a 4WD vehicle. The cost of parts, labor, and potential fabrication far exceeds the value of the end result, even if it's technically feasible. It's generally not a practical project for most people.
