We're using ZC 1.5.6b and PHP 5.6.4. Site is trackreadyproducts dot com

We've been selling items for one manufacturer and now are branching out to include a 2nd one; our needs I think are simple. If the customer orders item A from one manufacturer and item B from another (in the same order), the line items in the order should be emailed to their respective distributors.

I reviewed the various posts about drop shipping and I can't tell if there's a current plugin for our version of Zen Cart. Dropship PO looks promising but it appears to be shelved? Hope I'm wrong.

Thanks in advance.
