I agree it looks like full pan but here is one on SAMBA that says shortened pan (it wasn't built by current owner so he may just be guessing). There are 2 fairly near me for sale - one unfinished one for $8k and another for $13,500 that looks to be a nice ride. (Both red - maybe I can get Rich to buy one?)
Here's part of the advert from one -
Classic Motor Carriages 359 Porsche. Built on a 1971 shortened bug pan. 1641 Dual Port with dual carbs. I was told it was built by a VW shop in CA. Runs and drives great

Here's the $8k one - I think it would buff up nice.
