Does anyone know if the A pillars in a 1978 Delta 88 are specific to that car or do other models interchange? Are they the same as a 98? How about a Cutlass? I have a box full of A pillars from 1978-79 Cutlasses. I could use one of these if they're the same.
Thanks

 

Are you talking about the actual metal A-pillar or the interior cover? Windshields and thus A-pillars are the same on 1977-1985 D88s (and all other B-body cars), 77-84 Ninety Eights (and all other C-body cars), and 77-90 Custom Cruisers (and all other B-body wagons). Actual interior trim configuration may vary with trim package.

 

I just worked on the Pillar trim on a 87 Delta 88. I'm sure they are different every year with the model changes. I kind of forced mine off and then found there is two brackets that hold them on with bolts which are accessed from the inside. Should have removed the interior trim first.

 

A FWD 1987 D88 H-body is completely unrelated to the OP's 1978 RWD B-body.

 

The shop that replaced the headliner did an excellent job but did break a piece off the interior plastic A pillar. I'm surprised only one piece broke. 41 year old plastic pieces are brittle. Didn't know if the trim was the same as an A/G body only because I have a bunch of them in different colors.

You can see in the photo I'm pointing to the broken piece.
