I've seen the number before but it's been awhile.
I'm thinking its one of several low-performance carriers, but I expect someone in the Performance Forum will be able to give more exact info. If nothing else, 8 3/4 carriers arent exactly rare, maybe just swap another unit in? Be sure to replace with the same gear ratio unless speedometer accuracy isnt a big concern.

Default Re carrier help:

I have 2:76's in it now, I was changing to something a little lower. I bought 3:23's for a 489 off of Ebay, thats when I ran into trouble because I didn't have a 489. Thanks for your help though. Dave.

Arrow as far as bearings and such

they are all pretty much the same,pull it down and match up bearing and race assemblies,I have reused crush sleeves by tapping on them on a bar in the vise,backlash at 10 to 12,new seal and reinstall.

I cannot find a reference for the numbers that you listed.

1-3/8" small stem pinion... (aka. '741')...
Carrier casting numbers: 1820657 (1957-1964), 2070741 (1964-1972).
This assembly was typically used in low weight/low horsepower
applications through low weight/medium horsepower and high weight/low
horsepower applications.
Pinion depth and bearing preload is set with shims. Differential
bearing setting (ie. backlash ) is set with threaded adjusters.

1-3/4" large stem pinion... (aka. '742')...
Carrier casting numbers: 1634985 (1957-1964), 2070742 (~1961-1969).
This assembly was replaced by a phase-in of the 1-7/8" pinion starting
in the 1969 model year. 1970 RW (Plymouth and Dodge mid-size) were
the last models to use the 1-3/4" which appeared in a 2881489 case.
This assembly was typically used in high weight/medium horsepower
applications through high weight/high horsepower applications.
Pinion depth and bearing preload is set with shims. Differential
bearing setting (ie. backlash ) is set with threaded adjusters.

1-7/8" tapered stem pinion... (aka. '489')...
Carrier casting numbers: 2881488, 2881489 (1969-1974).
This assembly was introduced in 1969 and was phased-in to relace the
1-3/4" unit through 1970. Note: the 1-3/4" pinion also appeared in
some '489' carriers during this period. By 1973, the '489' was the only
unit available in passenger car applications.
This assembly was typically used in high weight/medium horsepower
applications through high weight/high horsepower applications.
Pinion depth is set with shims, preload is set with a crush sleeve.
Differential bearing setting (ie. backlash ) is set with threaded adjusters.

Those pics came from an auction on ebay. So, they will probably only be good for another month or so (before ebay removes the pics).
