Rob.. It just dawned on me...
Which carbs do you have ..??
The common round tops or the later 77-78 type with the cable choke..
They only pre-make the extended cables for the round tops..
If its a later set.. then they have to be custom made.. and spendy..

Build it the way you want it ..... then learn how to ride it like you own it..
