O2 sensor part numbers

[DGraber460 at aol.com]

I have 4 single wire O2 sensors with 3 different part numbers. Unfortunately 
I didn't document where they all came from.
Does anyone know if there is a specific application for each number?
The Bosch numbers are as follows;
        0258001041 (I have 2)
        0258001026
        0258001051 (known CGT donor)
For what its worth, the URQ isn't really fond of any of them. Since they're 
used, I think it's their condition, not the application. Any confirmation?
