72 280 se interior replacement

[jgranzier]

I was hoping someone might have experience with the interior on these 280 se
car.
I have a '72 and would like to replace vinyl dash and wood bow and vertical
pieces . ( vertical pieces that go left / right on windshield up to headliner)

I have the bow covered and the vinyl dash .

I do not see any screws on two vertical pieces - is this a "snap on"fit ?
( similar to the rear view mirror ?)

Thanks in advance - will post pics of progress
