hi guys,
i bought some new knobs for the side and front vent but its not clear to me how they fit.

do they glue on? they have a cross shaped slot at the back, one slot having parallel sides the other tapered.

if i push the knob on the arm with the arm located in the parallel slot its too lose and if i use the tapered slot it wont go on.

confused (yet again)

49 1/2 ton

what am i missing?
