I just put a late model 442 steering box in a 67 Malibu. The splines on the new steering box are much smaller than my old one. Any suggestions?

I upgraded my steering to a fast ratio box from a 94 Jeep Grand Cherokee. The rag joint shaft on a Chevelle is 13/16 and this changed later to a 3/4 inch. Here is a link that should provide some help

Jim Shea has done a lot of work on steering gear box conversions and you should be able to find him on the brakes and suspension form. Also, I would do a search for Lee Manufacturing on that forum. That is where I got my new rag joint from.

The original steering gear in the 1964-1976 cars had a 13/16 inch OD input shaft with splines and a flat. The new fast ratio gear has a ¾ inch OD input shaft. We will need a new flexible coupling to connect to the smaller shaft on the new gear. The following vehicles (with power steering) were produced with flexible couplings that will attach to the new gear:

1977 thru 1982 Chevrolet and GMC C/K (2 wheel and 4 wheel drive) Pickup Trucks
1977 and 1978 Camaro, Firebird, and Nova
1979 Nova
1983 thru 1986 Chevrolet and GMC C (2 wheel drive only) Pickup Trucks

I have found a flexible coupling in the GM parts system that will connect to a ¾ input shaft. It is available through GM dealers. It is part number 7826542. It is expensive (around $150 list) but it is brand new. Tom Lee has a supply of them. There are probably other A and F-car suppliers that have this flexible coupling available as well.

Thanks.......off to GM I go.

The GM one I got from Lee Mfg last year was around $83.
