The Stovebolt Site Forums The Shop Area Driveline Speedo cable part number

I'm installing a T5 transmission in my 1942 Art Deco 3/4 ton (BL). Does anyone have the NAPA part number for the 72 inch speedo cable that was recommended for this swap? Also, the T5 I bought has the red 9 tooth speedo drive gear. I'm running 6:00/15 truck tires that are 29.4 inches in overall diameter, and the OE 4.55 differential. The motor is a 1962 235, with dual Carter YFs, Offy intake, and Fenton headers. From what I've been able to research, it looks like I need to use a 22 tooth driven speedo gear. Can anyone offer some advice or confirmation for this speedo gear combination in my truck? Thanks.
