[TR] Alternative to Delco 10Si alternator?

Have you thought about just trying to change the bearings?  Not hard to do if you can find the parts.  I haven't looked for a long time, but Pep Boys and such used to sell "rebuild kits" with bearings, brushes and diode trios for about half the price of a rebuilt alternator.

Another alternative might be to buy a rebuilt alternator, and then swap your modified housing onto it.  That's what I did, years ago, when the front bearing went bad in my Ford alternator.

Sorry, can't help with a replacement that takes the same wiring.  The "mini" alternator I bought for next time takes a different plug than the 10Si and probably won't mount quite the same.
