[Cobra 29]

I replaced my 3550 with a new TKO600 in my ERA last year. While the transmission was a direct swap (e.g., bolt holes, overall size) the shifter collar and thus shifter was a bit taller above the transmission tunnel by 1/4 to 1/2 of an inch. I also installed a new shifter boot but it looked overly expanded. It seemed to "pull" on the shifter somewhat depending on the gear I was in. I called ERA and they sold me a 1/2" thin ring that mounts below the chrome shifter boot ring and the carpet. This raises the shift ring and boot so the boot does not pull on the shifter as much. Once the ring was painted black and installed above the black carpet it is bearly noticable.
