My Timkin Book lists Part numbers for 1922,23,25 and 28 but skips the year you need, but the numbers will be stamped on the bearings and the races, that will be the safest way to make sure you get the right one. Most if not all of the bearing should be avalabile from a bearing house or a good auto parts store, using those number.
I think the bearings were changed in the past with bearings and races that don't have any numbers stamped on them and really don't fit quite right either. I still need the right numbers.
Do You own a car built by Durant? 1926 Star Touring and a 1925 Star Touring Parts car that we are trying to put together.
