No one makes them for a 1st gen anymore. At least not the real good ones that bolt to the frame. You might find a used one here & there on Ebay or the black market here. The alternatives are the brush/grill guards that bolts to the bumper, but most of them are skinny looking.
Look at the other brush guard post below. Look into the 1 I got from JCwhitney. It has held up well & is plenty strong for my needs.
