The cheaper Lokar boot is too small to fit well. This entire process is touchy as centerlines are kinda tough to define.
The e-brake hole is that oblong hole next to the shifter hole

I also posed the same question about hole size for the shifter to Lokar....they just responded with the recommendation of using a 4" hole saw to cut the hole for the shifter. I don't know if I've seen a hole saw that big I guess it mostly depends on the type of shifter boot I decide on.....
