PMT* pcm part #'s

I am looking for a pcm for an 01 4x4.

As far as I know, a PMT1 is part# 1c3f-zb. There are also -za, zc, and zd. Are these PMT0, PMT2, and PMT3? I found some of these for sale at boneyards across the country.

I'll get the numbers tonight for pmt1 and pmt2.

2001 PMT0 1C3F-ZA
2001 PMT1 1C3F-ZB
2001 PMT2 1C3F-ZC
2001 PMT3 1C3F-ZD

Thanks. If I can't find a pmt1, are the 2's and 3's worth looking for?

Oh yeah....but don't expect to run one stock and like it. Using any of the popular custom tuner choices will net you a PMT1 base file anyway.
