Iis there a left and right defroster vent in a 63?

i recently took out the defroster vents in my 63 and also got a new glove box liner, now i can figure out how to get the defroster vent to clear the back of the glove box.

was wondering if there is a left and right vent and if there is a front and back. was thinking that i may have them mixed up and that is causing the clearance problems

thanks

got the answer today from Fred C, he mentioned that the glove boxes have a knock out that is removed. that took care of it
