If it was made out of balsa wood and paper mache it would be still better than the factory FJM front suspension.
I can believe that if there wasn't aftermarket torsion bars and steering boxes available for these. Traverse-t cars have every bit the same aftermarket support as a B body now a days.
My M has the FF 300# bars in it, a Borgeson box, FF tubular upper arms, solid K isolators, cop bars and modern tires. It out handles a lot of new vehicles.
