Don't you mean "742" case? 741 has the smallest pinion @ 1 3/8" and smallest variety of ratios.
Then there are aftermarket steel caps, aftermarket 489 nodular cases and the Mopar Aluminum 742 cases.

It might be the same Mirada GTX John mentioned, but I know of one that does run the 8 1/4".
Personally I'm happy with my 8 3/4". Car weighs 3,530+ but have only had broken teeth 2-3 times in 10+ years and the ease of swapping gears is too good to pass up. Current gears have been holding up for the last few years, but I have a set at Jim Bailey's right now.
