The raised lid (partly built) is almost three inches above the current trunklid and has a flat spoiler that extends to almost the end of the bumper. Accomplishing a really snug fit to the window and sides is difficult if I am to retain use of the trunk. A functioning trunk and visibility out the back window are essential. I'm wondering about fitting those rubber insulators used to seal household doorjambs into these gaps for the "snugness" that produces dead air under the raised lid.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
