Yup, sounds good.
I can't sufficiently measure the length equilizer to end (lever) on my BJ73 as it goes over the trany and bends. But 70 appears to be more in your needed range anyway. Hope it works for you. Good luck!
What's the plan? Fab those yourself?
The dimensions of the cables are probably your least problem, but the whole assembly, in particular the equilizer and connectors at the ends may be.
