Reinstalling my dash after a frame up resto and have a question about mounting this vent. I have an AMD cowl and there are no holes for mounting this vent on the driver side. Should I drill holes and use screws or self-tappers? Unfortunately I wasn’t the one who removed the dash so I’m not sure what it looked like assembled and I can’t seem to find any photos online. Also, better to do this after mounting the dash to ensure it fits?

Thanks!

The holes for the cowl vents have a lip about 1" tall around them. If you don't have that lip you could most likely get water in the car when driving in the rain or while washing the car.

Yes…I have that. I’m asking how the actual 90 degree L shaped vent mounts under the dash.

Originally 3 studs were tack welded to the bottom of the cowl so there are no holes for water to leak in.
you could use rivnuts & seal the threads

The whole is 7in. With 3 bolts to hold the fresh air box.

Of you don't have the ability to weld the three studs on, you can certainly drill holes and use rivnuts like Chryco Physco suggested. These actually work very well.
