I did that WAY back when I had power steering on the car for header clearance. Worked great.. It does throw the steering wheel center off a little. But it never seemed to affect the driveablity or handling any. Drove it that way for a number of years before I went back to a manual box.
I have an aftermarket front set up in my 68 fastback , but have done this modification to the stock k frame , (no motor mounts,I use elephant ears) for maybe future use ...
