1971 rearend 741 case questions

Yes Mopar made 2.76 and 2.94. I guess they were left of the list because of undesirability.
I know I wouldn't pay money for a set of 2.76 gears. Oh wait. I bought my son the valiant with the 2.76 gearset. I guess I would pay money for them. Lol. Do you think I should look for a set of factory 3.23's in a ten spline or look for a 489 3rd member then buy a new set of 29 spline 3.23's from Dr. Diff. ?Strange said the 1971 741 case is "a rare bird". Not sure why, I've seen many 741 for sale. I think the best option is to install the rearend as geared after a quick brake rebuild, and hoses. Then wait for Dr. Diff to add the 3.23 to his 741 line up. And keep an eye out for decent priced 742/489 3rd members to buy up.
