Interesting that the rule book states that the rear end can be replaced with another "
from the same manufacturer". Do the aluminum center-sections have a Ford part number? Is cast iron the only material allowed, or is the nodular case OK?
BTW - could anyone prove that someone's rear axle didn't come out of a truck if you removed the semi-floating axles?
Sorry you had this trouble, Ken. Hopefully it'll be nothing more than a speed-bump on the way to the winners circle! Good luck!
