THROTTLE CABLE QUESTION

This is a budget build. Just trying to used what i have. The cable is an original length cable. Not sure if its 2 or 4 bbl. Its 21.5 I need one thats around 23.5 -24. The bracket is just something i had laying around. Ill post some pics later Thanks for all the input O its a 360 4spd demon carb & eddy performer intake. The cable i have will line up with everything i have its just too short
