So to end this story its all working again.
What I did was since the main frame on the sides were a C channel and the top of the channel rotted off I found some new C channel and I inserted it inside the old channel since the bottom and sides metals were good . Then since my new C channel wasn't the same wide as the original I welded some 3/16 x 4 as a slide for the apron chain to slide on. Then I bent some aluminum flashing at a 90 deg angle . Attached to wooden side and extended out past the new 3/16 metal apron slide . I then cut an oil tank and flattened somewhat . Dropped it in and bent the front edge down with a sledge hammer so the cross bars would clear. Needed a couple slide ramps built as the apron chain has some slack. Everything has to clear the axle cross frame.
Anyways its good to go .
