door handle inserts

I am probably dumb, but are the door handle inserts the same for 70-81 because all the places I have looked only offer pre-70 and post-73. If anyone knows where to find them for 70-73 I would appreciate it, and if you could add the link and pn that would be awesome.

I found the door handle assembly at camaro central. they are black and chrome and it look good without the cups. they are 39.99 for each door. www.camarocentral.com I have not been able to find the door handle cups either.
