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!
