Found all of these in the trunk of a '69 Skylark convertible I'm parting out. I don't know Buick parts very well, so take a look & let me know what you might be interested in. I can get measurements, or better pictures also. I did find a set of Buick 455 exhaust manifolds, so some of these may be for a 455?? I think the Skylark just had a 350. Thanks.
