How close are these 2? Interior & parts wise. Can't find any interior for my Bonnie. I heard tell there about the same? What years? Bonnie parts on the nature coast of Fl is near impossible to find . Thanks as always for any info

bump it up

Iknow some of the exterior parts would swap but i think (may be wrong) that the interiors may be 2 different demons

The Bonneville and le saber both share the same factor service manual. I can't say for sure, but there'* a good chance many parts are interchangeable.

Both are H platform cars, Just about everything under the hood should interchange. Before changing transmissions verify correct gearing though.

suspension should interchange, but the Buick is going to have much softer spring rates then the Bonneville. When I repaired my ELC most of the parts I used came off a few LeSabres at the junk yard.

Some interior parts should interchange, what will will be very limited, All I know that works is the the plastic strips that cover up the divide on the front door windows do interchange.
