Paxton Supercharger question

[1968GT500CS]

Hello,
I bought a used, needing rebuild Paxton supercharger...is there any known information about date codes etc to date the part.  I am hoping I guessed correct to 1967.  I want to install on my 1968 clone project.

I have been told Craig Conley is the man for rebuild parts and service, will reach out of course.

Is there any database?  How to decode the stamping on the case?  Thank you in advance.

I have the pressure box and this supercharger so far, any parts for sale to complete?
