Here's another part number that works, a generic automotive trunk seal.
UWS139-25
Several places had no stock, so ordered through stylintrucks.com and it was quickly drop shipped from Precision Replacement Parts for less than Amazon's product.
Easy to install and a tight seal, as 2G reported. I sleeved the joint with a couple of inches of 1/2" OD Latex tubing, McMaster part 5234K12.
