I just picked up my Kouki and it's in pretty good shape but the shift boot is effed. I ordered a new knob and some material to make a shift boot (I know HOW to make it, watched the vids) but there's a problem.

All the tutorials say "trace/measure your current boot for a template".. but my boot basically doesn't exist. It was shredded and then the missing area is currently a cluster of electrical tape.. so I have nothing to measure. Does anyone have approx. dimensions of the stock boot, or know where I can find them?

I've been searching and searching and coming up with nothing. Thanks
