Technical Early sbc oil pan Id

Anyone know what this oil pan was from. It came on a 62 327, but was likely not original. It touches the cross member in my 59 El Camino, so I am thinking Vette, but not sure.

 

I think that's the mid 60s full size car pan.

 

Looks like can 70's chev pickup pan ..

 

mid 60s full size, i have several of them on core 283 and 327s in my shop.

 

Thanks guys. If anyone is tempted this hits the crossmember in the early X frame cars, and is a bear to remove with the engine in the car
