Well I guess I didn't strike gold.....
The intake on my car is "J 398662 '68-'69 400/455 4V All including W-30 and 68 H/O. Except Toro, 69 H/O. Iron" (from the Olds FAQ page) I searched the Olds FAQ and saw the difference with the ebay intake.. But $11,100???!! for an intake?
I'm speachless.... I guess it's all about the #s..
