hey guys i dont know if i am in the right place but here goes, could anyone say exactly where are the drain points located on the e30's at the rocker panel? reason i am asking is because i am restoring my car and i was testing my sunroof drainage by pouring water in the grooves. It runs out just fine but on the right side i notice about 4 spots in total. The rear at bumper, and three places just at the rocker area. The left side same at thing at the bumper area but only two spot at the rocker. i would like to know if i have rust holes anywhere and if i should block any up.
