You should be able to find similar double sided foam tape from most auto parts stores. The ones made by 3M are the best and are available in different thicknesses. For OEM, you may want to try parts.com (offline right now). It'll probably be sorted under "collision". Search on part.net is a bit tricky... might have to get creative on your choice of keywords.
I just check the VX parts listing doc I have. No part or part number is listed for the OEM adhesive. Looks like generic adhesive tape is the way to go.
