I was told today that I need to get a new, stearing box. I was quoted 560 installed for a remaned delco unit. He said that the only one I should get is for the SS with the FE4 suspention package, which is the sports suspention package. My question is, Is the FE4 Caprice the same stearing box as the SS stearing box? By the same I mean, is the gearing inside the Box the same? I can get one from the Boneyard for 100 bucks.
