Good To Know
Q: Will this linkage work with a floor shifter? A: This kit is designed for column-shift applications and typically does not fit floor-shift setups without modification.
Q: Is the adjustment range enough for a custom engine swap? A: The rod offers ample length adjustment for most custom installations, but measuring your shift lever position before ordering is recommended.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
