*** This listing is only for the \"Option B\" fulcrum height indicated below (for 10\" stick length); FOR OTHER STICK LENGTHS - DO NOT BUY THIS LISTING! - YOU NEED ONE OF THE OPTIONAL FULCRUM HEIGHTS not sold on eBay - go to our website.***
Shifter base for custom conversions using T4 & T5 transmissions sourced from:
- 1982-1987 Chevy S-10 & GMC S-15 pickup truck - except RPO M73 (Isuzu S101 4 speed)
- 1988-1993 Chevy S-10 & GMC Sonoma pickup truck - 2.5 & 2.8L only
- 1994-1995 Chevy S-10 & GMC Sonoma pickup truck - 2.2L only
- 1983-1987 Chevy S-10 Blazer & GMC S-15 Jimmy SUV - except RPO M73 (Isuzu S101 4 speed)
- 1983-1989 Chevy S-10 Blazer & GMC S-15 Jimmy SUV - 2.5 & 2.8L only
- 1983-2002 Camaro & Firebird - base fits, but is not correct in most cases
- The Camaro tailhousing crossmember mount is angled to match the original rotated bellhousing. If you use the Camaro tailhousing, you should use a Camaro bellhousing and a Camaro shifter which is angled to match. It is a poor idea to use a straight bellhousing with an angled trans mount as that mount is intended to be horizontal (will fail in constant shear); instead change to a S10 or Ford tail. If you insist on using a Camaro tail with a straight bell, this shifter base is the one you would use. But if you are using a Camaro rotated bellhousing, DO NOT BUY this shifter - see the special Camaro swap base with angled stub.
- 1982-1987 Chevette & T1000
- 1985-1989 Astro & Safari van
- 1982-1983 AMC Spirit & Concord (2wd)
- \"5-bolt\" base for AMC 4wd applications available by request
- Appears to also fit Isuzu T5
NOT FOR USE IN THESE VEHICLES - see separate listings for complete kits. For all other T5 models, see separate listings; T5 shifters are NOT universal! This base mounts on a rectangular 4-bolt pattern that is ~ 2.88\" wide x 3.44\" long; stub pivot ball center is ~1.2\" below flange.
A Hurst stick is required (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\"+)
- Note OE dust boot is short and exposes stick mount which helps in tight situations
- Options E & F require a Hurst stick directly mounted on side w/ serrations
Stub fulcrum height options (critical to optimizing leverage for short throw):
Option For stick length stick mount height stick mount angle boot type upcharge A 8\" 3.1 vertical Billet Plus default B 10\" 3.6 vertical Billet Plus +$10 C 10\"+ 4.6 vertical OE (short) +$20 D 12\"+ 5.4 angled 14 deg left OE (short) +$30 G 6\" 3.5 angled 11 deg left OE (short) +$10 H 5\" 3.0 vertical OE (short) +$10- 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, dust cover boot, and instructions. Comparable to discontinued Hurst # 3910040 & 3916110 + current base ending in 6045. The base is built by Core Shifters using proven Hurst Billet Plus components inside a custom housing. It does not have stops and does not need them; all modern internal rail trans have internal stops. This kit has many superior features & components, integrated into a unique, exclusive assembly:
- Forged heat-treated 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
- Rubber oil control seal with steel retaining ring
- 6061-T6 extruded aluminum housing with Spirolox steel support ring
- Zinc-plated laser-cut steel base-plate & cover
- Vibration-resistant serrated flange head steel retaining bolts
- Rubber dust cover boot (style varies)
- High quality & outstanding value!
