Rods a plenty! All Q-jet secondary rods interchange.
-Most WFOT tuning can be performed with changes to the secondary metering rods, and extreme fine tuning with secondary rod hanger changes. Secondary rod hangers are letter labeled B thru V, B being richest, V being Leanest. The changes effected by the hanger is how deep the seondary rods are hung into the secondary jets. Consequently a "B" hanger will "pull" the rod to its richest metering point quicker than say, a "D" hanger at the same amount of air-valve opening.
-Only a "V" hanger is available from GM. The expectation is that you bend the arms of the hanger to suit.
-The best source for tuning bits 'n pieces is junker carbs. A wide variety of secondary rods can be found, from lean rods to extremely rich rods from turbo vehicles. (Early 80's 3.8l Turbo Regals used a Q-jet for fuel management).
-If you want a custom secondary rod set, turn a pair of lean rods in a lathe to suit your tastes. The rods are chromed brass, so you will find over time that a machined rod will devolop some wear areas.
