Simple partition wall question
 

I am closing off a third car garage from the two-car garage with a partition wall. The surrounding walls are already drywalled. Do I need to cut portions of the existing dry wall back to attach the studs to each other or can I attach the frame through the existing drywall into the studs?

I'd really appreciate the help!

Yes
 

Yup , just frame the wall with the drywall between , no harm done.The only thing you may want to do is glue (PL 400) the stud to the sheetrock to keep it from moving and creat a gasket of sorts since there may not be a nailer behind the existing sheetrock.Also keep the new sheetrock about 1 inch off the floor on the new wall so it does not wick moisture from the concrete floor.This can cause mold to grow at the bottoms of the sheets.
Good luck on your project.:)
