489 chunk parts

I’m looking for 3.55 gears, sure grip (not cone type) carrier, and a large (7290) yoke matching the pinion splines; all to fit a 489 case.

I have a complete 489 case but it currently has an open carrier, 2.76 gears, and a small (7260) yoke with unknown spline count.

I also have a nice set of 2.76 gears (10 spline) for a 742 case and an open carrier.

I’m willing to trade (all but the 489 case) or buy the parts I’m looking for.

My 489 chunk is in the photo.
