Regarding the bearings, in 2005 I checked every bearing and race. All had Timken numbers on them, which seems to be the common number still used for cross referencing roller bearings. Napa and many others use their own part numbers, but can be cross referenced with Timken numbers.
Regarding the front inner cone (bearing) the Timken number is 14132, but the Hollander Interchange Manuel also states, "Note: 14130 and 14131 fit" that probably explains why some have these numbers on the inner bearings. (14130 was used on Fords until 47, and 14131 was used on Willys until 48, so there are probably more of these available).
Note, I have been told that "14132T has a tapered ID and will not fit".
Regarding the inner cup (race), only 14274 is listed.
I replaced a front inner cup (race) and it was not a tight fit. I used a bearing bond that could fill small gaps and that solved the problem. You can get bearing bond that will fill certain ranges of gaps or looseness, all very small.
