That is a good NAPA part # for the cable (615-1644), I've used it about a hundred times on SPF and CSX cars.
The O-ring on the trans end should be NAPA # 727-2115 and I use a little silicone too - little is key word.
I believe the clip for the speedo gear is Ford # cldz*17292*a and I usually use gear # cldz*17271*a
