You can go shackle reverse or foreward, I obviously went foreward. Its great caus its offroad only but if you wan to be able to DD it without alot of work I would put them in the rear.
Other than that, I used stock waggy 7 leaf springs, outboarded the hangers a little bit and it too me and a buddy 2 days to complete.
Steering sucks, a stock 77-79 FSB or F-150 tie rod with part of the explorer inverted y steering will work, but it leave the tierod very low and gives alot of flex steer. My next big mod is high steer
