Can you convert a fwd 1981 Buick skylark to rwd and if so how it has a 2.8 v6 i believe?

Yes, it is possible to convert a front-wheel drive 1981 Buick Skylark to rear-wheel drive, but it requires significant modifications. You would need to change the drivetrain, including the transmission and rear axle, and potentially modify the chassis to accommodate the new layout. Additionally, custom fabrication may be necessary for the driveshaft and suspension. This project can be complex and costly, so it's important to plan carefully and consider your mechanical skills or seek professional assistance.
