I have not seen or heard of one personally. However, Porsche or one of its' vendors has made one for just about every Cab or Targa model that they ever built. 914? I would contact Porsche and ask them. I have called them in the past about technical stuff that wasn't in the manuals or in the PET and they were always very helpful and prompt with their answers. Prior to 9/11 Porsche had a Customer Commitment dept. that handled such questions. (770) 290-3500. Hope this helps.
I think the other issue is that the 944Cab roof, when retracted, doesn't fit flat (or below) the trunkline, so making a hartop hide the pile of canvas would be aesthetically more difficult.
