Product Description
Genuine Saginaw 3-Speed Floor Shift Conversion Kit (NOS)
This is a rare, New Old Stock (NOS) floor shift conversion kit specifically labeled for Saginaw 3-speed manual transmissions, part number 502 8419. Saginaw transmissions were the workhorses of the General Motors lineup, found in millions of Chevrolet, Pontiac, Oldsmobile, and GMC vehicles throughout the 1960s and 70s. This kit allows you to convert your classic from a column-mounted "three-on-the-tree" selector to a sporty, precise floor-mounted shifter. Featuring a classic chrome handle and a black "pool ball" style knob, this kit provides both a performance upgrade and a period-correct vintage aesthetic. As an NOS item, it includes the original heavy-duty linkage, mounting brackets, and hardware that have never been used or installed.
Kit Includes:
- Saginaw-Specific Shifter Assembly: Main floor-mount unit with chrome lever.
- Linkage Rods: Dual rods specifically designed for Saginaw shift arms.
- Mounting Hardware: Heavy-duty base plate, U-bolts, and clips.
- Instruction Sheet: Original factory guide for Saginaw 3-speed setup.
- Original Box: Features the "Saginaw 3-Speed" designation.

Note on Installation: While this kit is designed for Saginaw transmissions, please verify your specific transmission tailshaft or side-cover bolt pattern to ensure the mounting plate aligns correctly. Some floor pan modifications are required for all column-to-floor conversions.
A Note on Saginaw Reliability: Unlike some modern universal kits, these vintage Saginaw-specific conversions were engineered with thicker linkage rods to handle the distinct shift gates of the GM Saginaw gearbox, resulting in a much more positive shift feel.
