[DeTomaso] AC clutch, p/n decoding

[Tomas Gunnarsson]

My AC clutch broke down and the coil uses abnormal amounts of electrons. :-)
I was given a leaking compressor with a working clutch that with a little
luck could act as a parts donor.

Broken clutch is marked:
Zexel
506 491-5870
965

Working clutch is marked:
Zexel
506 491-1261
470

Anyone with p/n decoding info on the list?

I have not yet had an opportunity to take them apart to compare visually.
