It is my understanding that the Moser housing is the one that has the 4 bolt setup. Two that moumt from the top and two that mount from the bottom. The Strange housings use the two bolt-bolt through factory setup. During my resaerch for an F-Body housing I've talked to many racers who use the Moser housings and have expereinced bolts backing out even when using loctite. This is something that you have to keep an eye on and make it part of your routine maintaince. I have never heard of bolts backing out of housings that use the two bolt factory setup. It seems to me that this is a housing design flaw and not a Torque-Arm design flaw. I would say that close to 95% of the racecars that I've looked under use the S&W torque-arm so that's the one that I went with. I just don't like the round tube front crossmember and mounting point because I seen some of the round tube flex upward under load. I redesigned mine to use 2x2 square tubing and a custom front mount to accept the square tubing along with some additional ajustability.
