I just purchased a 1981 633csi 5-speed for the front seats and was wondering if it is a direct bolt on project into my 1971 2800cs coupe? The seats are the 8-way manual Recaro factory BMW seats. Will the manual tranny be a direct bolt on piece? By the way if anyone is interested in purchasing the 5-speed tranny or any other parts from the car, let me know. The seats I am keeping. I am in the Los Angeles area.
