Slant 6 throttle cable

I'm having a tough time trying to locate a /6 throttle cable for a 1965 B-body. I need the extra length over the v8 cables. Are the A-body cable the same length? Stock v8 cables are 20" on the b-body. Con someone post the length of theirs? Thanks
The 65 B-body Slant 6 accelerator pedal is a special animal. I believe that you need one of these expensive cables. (Maybe someone has a reasonable OEM unit?) Mopar Throttle Cable NEW 64 65 1964 1965 B Body V8 TC6465BV8 | eBay
