My Mom's 87 740 GLE got hit hard and I want to swazp out her drivetrain into a 94 940 Turbo. Can the 87 non-turbo engine and tranny be swapped into a 940? I understand that everything after 88 had a camshaft sensor which my 87 engine doesnt have-If not what can I swap into 240 series or I guess am I limited to pree 89 swap candidates?Thanks in advance -
