Early A Body fan shroud EBAY Link

The '61-'64 shrouds (ring-and-legs style) are not the same as the '65-'66 shrouds (box style). There were '65-'66 shrouds for 19" and 22" radiator widths. Also the shrouds differ by engine; a slant-6 shroud won't work with a V8 or vice versa because of fan placement differences.

This what's in the auction appears to be a '65-'66 shroud for 22" radiator and V8 engine.
