• For all other T5 models, see separate listings; T5 shifters are NOT universal!

Mounts on a slightly trapezoidal 4-bolt pattern that is ~ 2.7" wide x 5.0" long; stub pivot ball center is ~1.2" below the flange. Applicable tailhousing casting numbers include 1352-066-908, 912, 919, 921, 935, 939, 953

A Hurst stick is required (NOT included, sold separately). Other brands and homemade sticks are discouraged. Stick mount has 3/8"-24 threaded holes spaced 7/8" apart on center + mating serrations for a Hurst stick on one face. Due to larger mounting threads (3/8"-24), sticks that use 8mm mounting bolts (most OE, "non-TKO" Lokar, others) will not work. Lokar TKO sticks can be mounted but only to the smooth side of the stub. To select the proper parts:

• Wait until new transmission is installed to buy shifter parts
• Remove existing shifter base if present
• Sit in vehicle, in driving position, with all interior trim (dash, console, etc) in place
• Define desired knob location in space (neutral position):
• Measure height from base flange to desired knob location = overall height
• Measure side & rear offsets from receptacle bore to desired knob location
• See this diagram for clarification
• Study the Hurst stick page for shapes that meet your needs
• Allow 3-6" for stick mount height
• Choose a stick and see what fulcrum heights are compatible with it (see chart)
• Check overall height (see chart: stick height + mount height = overall height)
• Confirm chosen combination achieves desired knob location and that fulcrum height works with stick length selected
• Consider various stick & stub combinations to optimize
• Note long sticks on angled mounts will strongly offset knob to left (can be 5-6"+)
• Options E & F require a Hurst stick directly mounted on side w/ serrations

Stub fulcrum height options (critical to optimizing leverage for short throw):

• Stick length = point-to-point distance from mount hole to knob thread
• Stick mount height = distance from base flange to stick bolt hole (affects knob height)
• Fulcrum height = distance from lower ball to fulcrum pin; varies by option, not published
• Warning: Follow stick length guide to avoid excess effort & component failure

Kit includes mounting hardware and instructions. Compare to Hurst #3916051. The base is built by Core Shifters using proven components inside a custom housing:

• Billet steel gear selector stub
• Hardened steel cross-pin & stainless steel fulcrum pivot ring
• Self-centering cross-gate bias springs with heat treated spring seats
• Glass-reinforced polyamide fulcrum socket with steel wear clips
• Extruded aluminum housing with Spirolox steel support ring
• Zinc-plated laser-cut steel base-plate & cover
• Rubber oil control seal with steel retaining ring
• Vibration-resistant serrated flange head steel retaining bolts
