Converting crib to toddler bed. We have lost the instruction manuel for our Simplicity Ellis 4 in

Question

We have lost the instruction manuel for our Simplicity Ellis 4 in 1 crib. We need to convert to the toddler bed. Can anyone help us? We bought this crib in 2005, I now understand Simplicity was bought out and the new company will have nothing to do with products purchased prior to 04-08.
