Since our trucks live at the edge of the coverage, Scott, I bit the bullet and purchased both the 1946-1956 Classic Car Parts Interchange Manual (Vol II) and the 1954-1966 Classic Car Parts Interchange Manuals Vol III (Parts A and B).
Pricy, but worth it to me even though I live in a place without salvage yards. Learning to read the darn things is a science in itself that I haven't completely mastered yet but the manuals have already helped me greatly in my search of overdrive tranny parts.
Now, if they would just put 'em on seachable CD's . . . I know, I know, I'm lazy
