59 power window install help

[spikes59]

Hi Did i buy the right power window kit? Dolphin window thru e-z wire,i have never put power windows in before so a couple dumb questions,I did not remove the brace that ties the inner and other door skins together and the window kit does not seem to fit on top or below brace,do i have to notch brace also it looks like i have to cut or shorten channel to get window to come down or up the right height and it seems like it still will hit the support brace in doors. any comments positive or negative or better yet point to where i can see pictures. i am keeping the vent window in. thanks mike.
