I ran into the same issue on my '74 K20. I ordered an aftermarket cable from LMC- they only offer one for a '74 that says it fits all models with a 350. After trying to install it, it was obvious it was too long and needed to be curled around to make it work. I did some searching and found a NOS cable instead. Pioneer makes the aftermarket cables, at least for LMC and O'Reilly. https://www.pioneerautoinc.com/all?subcategory=707

Their site says the correct cable for my '74 K20 is 23.54" long- which is way way wayyyyy too long.
