Help with throttle cable or rod

[JimmyCriswell]

I have a 68 longbed with a 350 quadrajet and a 5speed (nv3500). The PO literally had a coat hanger bent to operate the cable. I am not sure what type of cable or rod to use. Any advice? I was thinking about creating a throttle rod as I prefer those to cable. I don't know if there will be anything stock since 68s did not come with a 350 from what I understand.

Any thoughts would be greatly appreciated. Carb has all original equipment. I am just unsure of whether or not the gas pedal is stock. It does appear to be.
