'66 to '72 rear parking brake cable (interchangeable?)

[likaroc13]

i'm swapping to a '72 rear end on my '66 1/2-ton short bed...i need to replace the passenger rear parking/emergency brake cable on the '72...at Classic Parts, they show that the cable is the same for 66-72...however, LMC lists them with different part #'s....i was hoping to just swap the current rear cable from my '66 to the '72 rear end, so i don't have to buy a new one...but can anyone verify if they're the same?

thanks
