Alternate source for rear leafs?

Has anyone found an alternate source (meaning not new) for rear leafs? For example in the Jeeping world the '87 to '95 YJ Wrangler can use stock rear springs from an S10 and gain a little lift or rear springs from a Cherokee for a bit of a wheelbase stretch.

I saw the Durango thread where he built the bastard pack, but I would prefer to swap an entire set.

I know it may be a long shot because of the offset front to rear from the perch mounting area.

Thanks.
