Hurst Shifters

[3macs1]

Is there a site or posted information on how to identify original GM hurst shifters. I opened a crate today with quite a load in it that we put away 25 years ago. I want to make sure I identify them correctly. Many have 3138 on the side and yes some are 69 camaro but there is quite an arrangement of different handle styles etc looks like some maybe GTO, 442 and even a hurst olds.This is not over the counter stuff for the most part and pretty confusing right now. I think this one is 69 camaro

Thanks for the help
