440/727 shifter cable

Need to replace the shifter cable in 72 duster. The old cable seems to be short and makes a near 90* turn into tranny bracket. Its a 5' with double eyelets to a Hurst quarter stick. I'm wondering if a 6' would be better. Right now the headers are off so its tough to tell if a longer cable would fit in there.

What do you BB Duster guys have?
