Interesting. I've never seen that product before. I question what the lowered top would look like and highly doubt you could get a boot on it. Might it even stress the pump and frame folding it?

I know that, back in the daily driver years, even after being serviced and working to specs, my 68's AC would never cool the car down to where I would be comfortable after it has sat in the sun all day at work. That thin black top would radiate heat faster than the fan could pump out the cool.

I did notice in the Classic catalog it is made by Acme. Reminds me of Wile E. Coyote equipping himself to get the Road Runner.
