77 Argosy interior light cover removal help

[Lobi]

Playing with little things till winter let's up and let's me drive into some bigger projects.
The three panel lights (above sink and at each bed) seem to have tricky shades for removal. The cover needs to come off for cleaning and bulb replacement. Any tricks? Just bend in carefully and remove? Don't want to crack em thinking they might be a little brittle at 43 years old.
Also, main ceiling light in hallway and kitchen (round with 4 bulbs) looks a little discolored and melted. Thinking bulbs were a little too hot. Want to replace with led bulbs. Everyone having good luck with the (1156?) Chinese replacement bulbs?

I replaced all bulbs in 76 AS & all rear lights w/cheap led [$10.00 for 20 1156 style bulbs on Ebay] all working after 3 yrs. You do not need fancy expensive led assembly for any lights just bayonet style.
