Peterbilt Chrome gearshift sleeve and collar. Covers those hideous air lines for a very clean look. May be used with balck factory knob or most other aftermarket knobs, which may be purchased separately. See page HANDLES AND KNOBS for shift knob styles. Made for 13*15*18 speed transmission or 9*10 speed. Sorry, no "super" 10. Made in the USA by Switchcraft.
