Crooked alternators

[Eagle Kammback]

So my friend was taking care of my truck while I was away for half a year, and the alternator went while he was doing it. So I sent a one wire alternator back and he put it on. But theres a spacer tube or something like that that we forgot about. Long story short, it got worn out and crooked. So learning from our mistakes, I bought a new alternator and made a spacer for it to keep it flush, but that alternator also wore out and got crooked.
Are there any alternators I can get that have an integrated spacer thing?
