Way back when, probably almost 9 years ago, when I went with the Oz head and Weber 38DGAS carb, I ran the Lokar throttle and kickdown cables and pedal.
Universal / Adjustable Throttle Cable 0625TC-1000U36 $32.99
Trans Kick-Down Cable 0625KD-20C4HT $53.99
Billet Alum Gas Pedal 0625BAG-6004 89.99
Riser (Lokar pt. #) GPS-6014 $30.00 (+/-)
(Note: the prices are about 9 yrs old, they may have changed over the yrs.)
