NOS Deep Groove Pulley ID help

[Fast67VelleN2O]

I just bought 2 NOS deep groove pulleys. Both of them part number 1-3770245 Group 1.062. If anyone can ID them for me that would be great! Thanks in advance

Hi Matt:
Also 62-68 corvette, 409's and I have even seen them although the books don't say it on full size with air http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif
Quite common.
take care
