Blazer Interior Plastic Interchange

[mcmlxix]

My 1978 Blazer has some missing and broken plastic that runs up the A Pillar and the B pillar (under the seatbelt top mount) and across the roof. What years will interchange? Are there any Suburban parts that fit? I would assume the A pillar parts are the same. Was there a plastic piece that ran across the top of the windshield. (My sun visors are missing too) What about a Blazer headliner?

IIRC the 73-80 A-pillar trim is a little different from 81-87 trim, a little "leaner". And there is a piece of trim across the top of the windshield inside. I think the B-pillar trim is the same, if there's a difference I haven't noticed before. The headliners thankfully are reproduced with a composite back instead of cardboard. Usually plenty of them on ebay. I've got some 81-87 trim boxed up that I can compare to my 79 if needed.
