The bottom one was advertised as the Hurst Mystery Shifter . It was an inexpensive shifter that was sold aftermarket and was O E M on Pontiac G T O's in 1964. The shorter one , uh can't say ................ scrubba
The top one looks very much like the OEM shifter that came in my '75 Camaro, but it was not a Hurst. Do you raise the handle to engage reverse?
they are both hurst style that came in production style cars. they are not the same as a Hurst comp plus. but they are interchangable. no thats NOT a mystery shifter. if you realy want to know what these shifters are how about better pictures??
