66 dart gt convert resto

found a good deal on another used 3.23 chunk. turns out its junk. the ring gear is pitted and so are the carrier bearings. i got my $ back so now i have 2 741 cases to work with. i will probably just buy a new sure-grip carrier and gears since i cant seem to find a decent used set. might as well spend the extra dough 4 new stuff. couple guys i work with have convinced me to go with the 3.55 instead. i love it when i am looking 4 parts and the ad says to "call 4 price" which pretty much means if u have to ask, u cant afford it.
