Trying to figure out if I can use any g-body A-pillar or if it has to be a 81-87 cutlass. I looked at one off an 79 Malibu 2 dr and it looks the same but still not confident. Also need to replace the tray under the back window but so far I've only found the tray for a 78-80 cutlass. Any advice would be helpful. Thanks in advance!
