what is the problem with your? did the tab snap? if so i repaired mine with a piece of sheetmetal. i cut a hole big enough screw the cable back on the the speed sensor. then drilled a hole for the screw. i used a 1/4 nut as a spacer and it fits perfect. no leaks at all.
i do have a XR2 cable but i am keeping it around just in case. like you said they are golden!
as for NA 5 speeds. i got 2 of them if anyone one needs one.
i will go take a photo now so you can see. no leaks at all once i did this.
