Physically I think a 71 E body steering column will work in a 70 Cuda. The 71 Steering column has the wiring harness in it, is it the same wiring harness as the 70 or do I have to switch it out? The is a reason I have to use the 71 and not the original 70. It has to do with the lockout linkage and the exhaust pipes. The pipes where put in before the linkage and now there is not enough clearance to put the linkage in.
