Looks like plans for the Jim P. version are fairly well documented, now that we know about the 1/4" thickness dimension:

Q-talk 128 - Swing Bar Canopy Installation

Note the middle where it talks about gas struts in windy conditions... I can also add that if I never have to have my face 2 inches away from a compressed 200 lb gas strut while curled up in the foot well doing a replacement,  it won't be too soon!
