Hi, Ben
Here is a link to a web page I put up several years ago, showing an easy spf hardtop storage system. I forget who's garage this is (not mine!) but another spf owner shared these photos with me several years ago when I was looking for a better way to store my hardtop.
Superformance Hardtop Storage
Simple, but works great!
I had been using a hardtop hoist attached to a roof beam in my garage, but always felt a little nervous parking under it in the summer when the hardtop was being stored :-)
I copied this setup - basically two boards mounted lengthwise on a wall, with a couple of hooks I picked up at a local Lowes. I have the boards spaced 21" apart on center and the hooks 31" apart. You want to support the hardtop by the hooks on the straight section under the back window and let the front edge rest on the lower board.
Hope this helps,
Jim Kellogg
