Background: There are two ways to approach a swap - you can either spend $$$ on an aftermarket trans with offset shifter that fits your console perfectly but doesn't have a short throw - or you can buy a used OE trans and with some effort (and maybe a new console) get a better result at a lower cost. We offer straight-stub swap bases for most RWD 5 & 6 speeds and unlike the custom guys, we offer multiple fulcrum heights so you can actually get a short throw with any stick length - at a reasonable price. This direct-fit (straight stub) approach is simple and works great, but often requires floor and console mods.
Core Shifters' swap bases for custom (non-OE) conversions:
- Designed & assembled in-house by Core Shifters
- NOT for OEM replacement in original applications - see complete kits
- Hurst stick required (sold separately). Other brands do not fit properly; homemade sticks lack material integrity. Never use a welded, bent, or modified stick as this creates a weak spot which can lead to catastrophic failure. Stick mount has 3/8"-24 threaded holes spaced 7/8" apart on center; sticks that use 8mm mounting bolts (most OE, "non-TKO" Lokar, others) will NOT work. The stick mount also has mating serrations for a Hurst stick on one face; only Hurst sticks have these mating serrations. Lokar TKO sticks have 3/8" holes and can be mounted but only to the smooth side of the stub and will need to be glued in place to avoid loosening... do it right, buy a Hurst stick
- Stick must be directly mounted onto stub; these bases are not appropriate for use in offset or remote assemblies. If you need a remote linkage, you chose the wrong transmission. These types of shifters are best left to the OEMs as doing it right (and safely) is very expensive and requires a transmission designed for this purpose. It is cheaper, safer, and easier to choose a different transmission that better suits your needs directly, or find an OE configuration that fits (e.g. 2004-2006 GTO, 2005+ Mustang, 2009+ Challenger, 2010+ Camaro)
- Proper leverage requires matching stick length with base fulcrum height. No base is "short throw" by itself. The stick and stub together form a lever; if you want that lever to have a short throw, buy parts that work together. Excess leverage can also lead to component failure
- Choose the stick and base together after the swap is done, when you can sit in the vehicle - these parts are not needed until that point and should not be purchased until then; DO NOT buy a base until you can also determine the stick! If you can't do that yet, come back when you can
- Focus on choosing a stick and base that together achieve your desired knob location in space. Do not focus on the stick alone. Consider the height and shape of the overall assembly
