They are not the same.

'69 307/327 used the same design frame bracket as '67-'68 302/327/350. '69 302/350 used a new design [3945507/3945508]. The 69 302/350 brackets were designed for a different motor mount that does not interchange with the mount used on the '67-'68 style frame brackets. Problem is, the '67-'68 motor mount fits on the '69 302/350 bracket. It is a poor fit, wider and shorter than the correct mount. Can cause clutch chatter and driveline vibration. The correct mount is a snug fit on the brackets.   

If the #5 spark plug seems too close to the steering gear, probably have the wrong mounts.

The factory assembly manual shows bolts from top; nuts/washers from the bottom. I have heard some Van Nuys cars were assembled opposite of the manual.

Both frame mounts on my car have the top 2 bolts inserted from below (through the subframe) with shouldered nut on top side, and the single lower bolt inserted from above.
