2002 Alti, First O2 sensor...threads shot, size to retap ?

Finally got out the pre O2 sensor, and it was cross threaded, so need to retap the hole &/or put in a thread insert in the manifold/pre cat area...does anybody know what the M thread size is for this sensor ? Do any of the auto parts guys "rent" out the tap for this like they rent out the sockets to get these out ?

Thanks,
F
