Kerf Fitted Weatherstripping for a Ceco Entergy Door

I own an home built in 1985 with Ceco Entergy doors. The door has kerf fitted weatherstripping, but the stripping is very thin, and doesn't have the bulb found on most kerf fitted weatherstripping I can purchase a local hardware stores. The doors are difficult to close and lock with the kerf fitted weatherstripping I can find.

The product I can find is available all over town.  Here's a link to the product on the Menards Web Site.   It's got a decent picture.

The folks at Alexander Lumber in Champaign were very helpful, but could not find a suitable product.  Still I'd recommend paying them a visit, they were knowledgeable and took time to answer all of my questions. 

The folks at Pella Windows and Doors have also spent time offering advice and corresponding via email.

The bottom line I am really stuck.  I've contacted the original manufacturer, who referred me to various distributors and business who carry their products.  I've reached out to those folks via email and phone.  Most have been quite helpful, but I still haven't found a suitable replacement.

I am open to suggestions. Here are photos of the replacement product and what I used to have.   The replacement product on the left side and is white.  The old product is on the right and is black.

The new product is filled with a foam or padding, and the original is hollow.
