Trunk Support Arms

[1980 911SC]

Just purchased my first Porsche, a red targa 1980 911SC. I have lots of questions, but let me start off with something simple. Does anyone know the correct Strongarm part number for the front trunk support arm? I have seen part 4454 listed, but a comment on Amazon.com stated that it was the incorrect part number.

I have already replaced one of the back support arms. The individual that I purchased the car from was a middle man, so he didn't know a lot about the vehicle. However, he told me that the whale tail was added. (Hence the A/C condensor coil was removed and not replaced) Was the whale tail not a standard feature for this year? Incidentally, my order for the rear trunk only came with one arm, but it holds fine.

Thanks
