I have 3 NOS after market shifters, one 3-speed and the other two 4-speed's. They appear to be from the early 70's. Made by "Serco Speed Equipment Reasearch Company" Seattle Wash.
All 3 are floor Shifters.
The 3 speed shifter is a generic install for a 3 speed Saginaw or Muncie.
One 4 speed shifter is also Generic installation for a Saginaw or Muncie.
The last 4-speed shifter lists it for a 1969 Nova, without console, Muncie or saginaw trans. It also includes a shifter knob in the shape of a Bowtie (not a chevy emblem but more like a rounded off bowtie). The 4-speed shifters are listed as "Magnum400" and has a P/N CY-69M
The apear to be quality parts, but no one I know has ever heard of the brand.
I and can't find any info on them. Or the company.
Any leads greatlly apreciated!!!
