Just thought I would report - I was able to fabricate some parts
out of aluminum channel and steel channel based on Dave's design
and document. Mine was done without welding since I am not a
welder, but riveted to the side rail. An additional piece of
aluminum sq tubing was added to the shell behind the side rail as
piece of mind should the side rail want to twist. I am happy to
report that after gradually torquing the jacking bolt, and shifting
the top maybe 1/4 inch, the shell closes a lot better. I needed it
more on one side than the other and this design helps addresses it
well. I highly recommend this approach if you find the closing the
trailer top is difficult on your fiberglass Cobra and see clear
evidence of the top shifting fwd. It took me one week, couple
hours each evening to fabricate the pieces and I'm not a
machinist.
