T5 transmission to Slant Six OD bell housing adapter

Thanks, if you can, concerning the QT bell that will bolt to a slant, can you get to me:
A contact name at QT
A date or time period that housing was made
A purchase number, part number, something that would trace back to the engineering data.
Thanks again.

I spent a full hour on hold with Holley today and never a peep on their end. So tried another way by emailing them for duplicate information on my order for the Quick Time housing. Hopefully this will work.

I did find the adapter rings in their original packaging but no documents were found. Did some spring cleaning about a month ago and the box it cam in was thrown away.

Last chance is maybe a number is stamped on the housing but I have all my lifts tied up and will be a couple of days before one is cleared.

Keep your fingers crossed as I'm not one to easily give up!
