B & M shifter cable routing

I use a 5 footer, and route it from the shifter to the passenger side, under the pan and back up on the drivers side to the trans. I wish that they made a 4 1/2 footer. I have a brand new 4 footer and 3 footer, can't use but I tried. I also use a https://www.summitracing.com/parts/dei-010418 over the cable, fits perfect for a 5 foot cable. Car is a '66 Valiant 2 door post with a 340/904
