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.)
