Dont bully me with your prices hahah. I paid 900 aus for a B body 8 3/4, jesus christ they are heavy as hell nearly blew my a hole out lifting it. To make it even more expensive my gladiator broke down on way to pick it up so thats fun. Just done a trutrac centre and the standard gears for now (Think around a 3.4), will swap gears down the track once chasing times. Hopefully the trutrac holds together i killed one in my ute but it was due to blowing a pinion gear to kingdom come etc.
Seen a lot of articles about the Ford Exploder diff looks like very good bang for buck conversion, sadly none here lol
