I have two oil pans as pictured. The red one came on a 1959 261 it may or may not be correct for that year. But that's ok, my concern is the chromed oil pan.
I would like to know what year the chromed one was made for.
I bought it as NOS and the only thing that the box said was "Group No. .462" that might have read #1.462 but the edge was torn off. Also is does say that the "Oil Pan Assy. part No. is #3756603.
But it does not state for what size or what year it was for.
I was hopeing that someone may have a Chevy Parts book that has this number listed in it that would tell what year it is.

Thanks,
Ed
