7-1/4 inch axle bearings

That number (41164000) shows in the Rockauto catalogue as for a 9 inch drum axle ie. small bearing.......

They show 41163000 as being for 10" drums or, 7.25 rear with front discs (my car), large bearing.

I did find another number, RWC35YYR, Timkin, Federal Mogul, Bower, BCA, Car Quest all use that same number, and, I'm pretty sure it's the large bearing.

Same companies part number for the 9" brake smaller bearing is RWF34R.

Mopar number for the bigger bearing kit (comes with bearing, retainer, seal, and two gaskets) is 3420091

I think, can anybody confirm this, or, have additional information.

Thanks, Al(BWA)
