I made my own out of 5/8 OD s/s springs and to s/s flat washer tack welded on the end on the spring and then drilled and taped for to machine screws in the flat washer, This piece bolted to the cowl side. drill 3/4 hole in door side and install plastic bushing for the spring to go through. My looks real neat. If you want photos let me know and I will takes some Monday and send them to you. I bought everything I needed for about $15.00 dollars at Lowes. You can open your door to a 90 degree angle and the spring stays round and does not kink.
