The side that is up in the picture is the pass. side. The wider side or thicker is the drivers side. Your engine should be offset towards the pass. side. Radiator is more to being centered.
Hope this helps.
Engine location I believe, fan is a little low, depending on shrouds application. Different shrouds for different car/engine combination, fan size etc.
I did not realize that there were 2 pictures.
The thin side is pass. Thicker side drivers.
Hoses, maybe.
I have both 614 V8 shroud and 049 slant 6 shrouds here. I found the offset fan opening exactly opposite. So the slant shroud could be installed upside down in a V8. The relief for the ears of factories formed wire hose clamp isn't a deal breaker.
